Wolong WPM/WGM series — compact PMSM motors built specifically for robotics, with an integrated holding brake (fail-safe, engaged without power) and a 23-bit absolute encoder. The slim, elongated housing with an H-series flange reduces the diameter of the robot joint. The 0.05–7 kW range covers all six axes of manipulators with 5–500 kg payload.

• 0.05–7 kW per axis, 0.16–47 N·m torque
• 17–23 bit/rev absolute encoder (multi-turn with hot-swap battery)
• Integrated electromagnetic brake with ≤ 30 ms engagement time
• Peak torque 3–4× rated for 1–3 s
• IP65 shaft sealing with Viton seal

Inovance is the only brand in our portfolio offering a full robotics stack: servo drive (IS620P, SV630P) plus motion controller, PLC and HMI. The SV630P supports EtherCAT with a 125 µs cycle, integrates STO/SS1/SS2 functions per IEC 61800-5-2 and auto-tunes the torque loop. It is used in manipulator control cabinets and in single-axis positioning systems.

• EtherCAT CoE / CSP (cyclic synchronous position) support
• Integrated STO, SS1, SS2 safety functions (SIL3 / PLe)
• Torque loop response ≤ 1 ms
• Auto-tuning of inertia and torque load
• Protection: IGBT overheat, encoder fault, torque overload

INVT DA200 — servo motors and drives for XYZ portals, linear modules and feed axes. They support EtherCAT, CANopen and Profinet and pair with INVT PLCs to build a multi-axis cell without a separate motion controller. Used in laser cutting gantries and assembly lines requiring 4–8 axis synchronization.

• Multi-axis synchronization over fieldbus (EtherCAT/Profinet)
• Compatible with rack-and-pinion and ball-screw drives
• Integrated regenerative module or external braking resistor
• Direct torque/speed/position control modes
• Single-micron positioning accuracy with 23-bit encoder

Mobile in-plant logistics platforms (AGV/AMR with 100–1500 kg payload) use low-voltage 24–80 V DC servo drives connected directly to a LiFePO4 battery. Each driven wheel is an independent servo with an integrated gearbox (drive wheel unit) or an external planetary gearbox. Wolong WPM-LV and Inovance IS810N serve as traction and steering drives.

• 24–80 V DC battery supply (low-voltage series)
• Regenerative braking with energy return to the battery
• IP65 protection against shop-floor dust and coolant splashes
• Dense low-speed torque for starting and maneuvering
• Encoder resolution sufficient for odometry (≥ 4096 ppr)

Besides the robot itself, a robotic cell runs feed and discharge conveyors, indexing tables, transfer units, clamps and unloading systems. This is the natural domain of general-purpose Huali Y2/Y3/YE3 motors (0.18–22 kW) and compact IE3/IE4 motors integrated into Boneng K/HB gear motors.

• IE3 or IE4 efficiency class (per customer specification)
• VFD-rated insulation (Class F)
• IP55 minimum for shop-floor service
• Flange-mount execution for gear motor integration
• PTC or Pt100 thermal protection

X-Y-Z portals and single-axis linear modules use low-backlash planetary gearboxes (≤ 3–8 arcmin) with a servo flange for Wolong WPM or INVT DA200 motors. Ratios i = 3, 5, 10, 25 cover the full feed-rate range. Long rack-and-pinion gantry axes use a planetary gearbox with a preloaded drive pinion.

• Backlash ≤ 3–8 arcmin (precision / high-precision class)
• Servo flange for standard motor frame sizes
• Torsional stiffness ≥ 14 N·m/arcmin
• Compatible with module m = 2–5 racks
• Service life ≥ 20,000 h at rated load

Boneng K (helical-bevel) and HB (industrial bevel-helical) series drive part-feeding conveyors, discharge lines and intermediate buffers around the robot. SF ≥ 1.3 because the duty is continuous S1 in automated operation. They are usually paired with a VFD to match conveyor speed to the robot cycle.

• K-series (helical-bevel) or HB-series (horizontal industrial)
• Service factor ≥ 1.3 for S1 duty
• Compatible with INVT/Inovance VFDs for speed control
• Optional encoder on the high-speed shaft for robot synchronization
• IP55 protection

Indexing tables and welding positioners use Boneng W/K worm or helical-bevel gear motors, either self-locking (worm pair) or fitted with an additional holding brake. Position accuracy is delivered by a separate mechanical system (Hirth coupling, index pins); the gear motor handles only the transition between positions.

• Self-locking (worm pair) or integrated brake
• Ratio 30–80
• Low vibration at stop
• Encoder-compatible for position feedback
• Rigid mounting for vertical load from the table

Compact Boneng HB gear motors and drive wheel units for AGV/AMR with up to 2 t payload. The all-in-one design combines a 24–48 V DC servo motor, a planetary gear stage and a rubber wheel. The ratio is matched to a top speed of 1.2–2.0 m/s.

• Compact drive wheel unit (motor + gearbox + wheel)
• Ratio matched to 1.2–2.0 m/s travel speed
• Low noise (≤ 65 dBA for night-shift logistics)
• Sealed gear housing against dust and coolant ingress
• 15,000–20,000 h service life before overhaul

A fail-safe electromagnetic disk brake (spring-applied, electrically released) is integrated into Wolong WPM/WGM and Inovance MS1 servo motors. When power or the enable signal is lost, the spring presses the friction pads onto the disk within 20–30 ms, holding the robot arm against gravity. Brake torque has a 2× margin over the axis holding torque.

• Spring-applied (fail-safe per DIN VDE 0580)
• Brake torque ≥ 2× motor rated torque
• Engagement time on power loss ≤ 30 ms
• Service life ≥ 5 million engagement cycles
• 24 V DC ± 10% coil supply

Palletizers and 200–800 kg manipulators carry a dual brake system: an internal motor brake plus an external electromagnetic disk brake on the gearbox input shaft. Both engage simultaneously on emergency stop (E-Stop, guard door opening, torque overrun). Stop category per ISO 13849-1 is Cat 1 (controlled stop) or Cat 0 (immediate de-energization).

• Dual brake system (internal + external)
• ISO 13849-1 stop category 0 or 1
• Compatible with the drive STO signal
• Engagement time ≤ 50 ms on the redundant brake
• SIL2/PLd functional safety certification

When a servo motor decelerates, the kinetic energy of the moving mass is fed back into the drive DC bus. Without dissipation, DC-bus voltage exceeds the threshold and the drive trips on overvoltage. The solution is an external braking resistor (for moderate cycles) or a regenerative module returning energy to the mains (for intensive pick-and-place machines and palletizers). Both variants are supplied by Inovance and INVT.

• Dissipation power sized from the duty cycle (peak and average)
• PWM-rated braking resistor with thermal protection
• Regenerative module with EMC filter for mains feedback
• Drive-compatible interface (shared DC bus)
• DC-bus overvoltage protection

Mobile platforms use electromagnetic brakes integrated into the drive wheel unit. They engage when the enable signal drops, when an emergency-stop sensor triggers (bumper, safety laser scanner), or when the battery falls below a critical level. Heavy-payload platforms also carry a parking brake with mechanical lockout for long stops.

• Fail-safe engagement on power loss
• Trigger from a safety laser scanner signal
• Brake redundancy across multiple wheels
• IP65 protection against shop-floor dust
• Compatible with AMR control stacks (ROS / VDA 5050)

Ball-screw drives in linear modules and gantry portals use Yongjing bellows couplings with zero backlash and high torsional stiffness. They link the servo motor shaft to the ball-screw. The thin-wall bellows compensates 0.1–0.3 mm / 1–2° of radial and angular misalignment while transmitting torque without loss of positioning accuracy.

• Zero backlash
• Torsional stiffness ≥ 5,000 N·m/rad
• Axial misalignment compensation 0.3–0.8 mm
• Balanced for speeds > 3,000 rpm
• Clamp hub with split shaft for fast mounting

Feed conveyors, discharge lines and rewind spindle drives use classic Jiaohua YOXp / Yongjing LX pin-and-bush flexible couplings. They damp start-up shock loads and compensate 0.2–0.8 mm of misalignment. They are compatible with standard Boneng K / HB gear motors.

• Torque 5–125 kN·m
• Radial misalignment compensation 0.2–0.8 mm
• Elastomer life ≥ 20,000 h
• Bush replacement without removing the machine
• Compatible with standard IEC flanges

Indexing tables that rotate to fixed positions (90°/180°/index slots) use jaw-disk couplings that absorb misalignment between the gear motor and the table shaft. They transmit high torque during short start/reverse cycles and need no lubrication over their service life.

• Torque 50–2,000 N·m
• Angular misalignment compensation up to 1°
• Lubrication-free polymer elements (PU / Hytrel)
• Low inertia for fast acceleration and braking
• Encoder-ready hub on one half

Long ball-screw drives (2–6 m stroke) use diaphragm couplings with a stack of thin steel disks. They transmit high torque at minimum backlash and absorb misalignment from screw thermal expansion. Typical applications are laser-cutting gantry axes and assembly-line linear portals.

• Zero backlash, high torsional stiffness
• Axial compensation for screw thermal growth (up to 1 mm)
• High rotational speed (up to 8,000 rpm)
• Steel diaphragm life ≥ 50,000 h
• G2.5 balancing for smooth rotation
