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: What are the differences between planetary gear motor and worm gear motor?
A: Planetary and worm gear reducers differ significantly in structure and performance. The planetary reducer uses a cylindrical gear system, offering higher load capacity, greater precision, and better stability than the worm gear reducer, which relies on a worm-and-wheel mechanism. Planetary reducers are compact, have low backlash, high accuracy, long lifespan, and deliver high output torque. Worm gear reducers, on the other hand, provide self-locking capability and high reduction ratios, with input and output shafts on different axes or planes. However, they are larger in size, less efficient, and lower in precision.
