High torque BLDC motor for robot actuator programs

Capability Highlights

  • High slot-fill stator and strong NdFeB magnet options
  • Custom winding for voltage, speed, and current limits
  • Frameless, housed, and integrated driver configurations

Typical Applications

  • Robot joint motor cores
  • AMR and AGV drive wheels
  • Compact industrial servo axes
  • Medical and laboratory automation

Engineering Focus

  • Kv, Kt, phase resistance, and inductance matching
  • Magnet grade and demagnetization margin
  • Winding temperature rise and continuous torque boundary
  • Driver current limit and commutation feedback

Key Evaluation Matrix

MetricTypical RangeWhy It Matters
Torque ConstantCustom Kt by windingControls current demand, heat generation, and driver sizing for the target torque.
Voltage Platform24 V, 48 V, 60 V, 72 V customAligns the motor with battery, controller, and certification constraints.
Continuous TorqueDefined by thermal path and duty cyclePrevents selecting a motor by peak torque only, which can fail in sustained operation.

RFQ Checklist

  1. Share target voltage, no-load speed, and torque-speed point
  2. Define continuous current, peak current, and thermal condition
  3. Confirm hall, incremental, or absolute encoder requirements
  4. Provide mechanical size limit, shaft style, and cooling assumptions
  5. State whether you need frameless kit, housed motor, or driver integration

Risk Controls

  • Peak torque over-promising: Quote peak and continuous torque separately with current, temperature, and duty-cycle assumptions.
  • Driver current mismatch: Match winding resistance and inductance to the buyer controller before prototype production.
  • Magnet demagnetization: Select magnet grade and temperature class against overload and ambient requirements.

Buyer FAQ

Can winding be customized for our battery voltage?

Yes. We can tune Kv, Kt, resistance, and inductance around 24 V, 48 V, 60 V, 72 V, or buyer-specific platforms.

Do you offer frameless BLDC motor kits?

Yes. We can supply stator/rotor kits or housed motors depending on your mechanical integration model.
