Note:
- This torque value is the rated output value of the reducer, not the final motor + output torque value T after reducer.
- The formula for calculating the output torque after the final motor + reducer: T = rated torque of the motor * reduction ratio * 0.6, and T≤ rated allowable output torque value of the reducer.
Dimension (Unit: mm)
Mounting screws are included with the gearhead

Details

Speed - Torque Curve
- Instantaneous maximum torque line: The maximum torque momentarily impacts the load when the motor is started. Exceeding this level triggers the driver's over-current protection, shutting down the motor.
- Short-time operation area: The motor can operate within this torque range for limited periods at different speeds. Prolonged use generates excess heat, which may cause the motor to stop or burn.
- Rated operating torque line: The rated torque of the motor can sustain at different speeds for continuous, long-term operation.
- Continuous operating area: When the motor rotates at different speeds, it runs continuously in this corresponding zone.

Q: Why does DC worm gear motor produce vibration?
A: BLDC worm gear motors usually produce vibration due to issues such as poor gear meshing, rotor imbalance, worn bearings, poor brush contact, or loose installation. These problems can lead to uneven torque output or structural resonance during operation, resulting in mechanical vibration and noise.
