Note: This torque value is the rated output value of the reducer, not the final motor + reducer output torque value T.
Final motor + reducer output torque calculation formula: T = motor rated torque * reduction ratio * 0.6, and T ≤ reducer rated allowable output torque value.

Speed-Torque Curve
- Instantaneous maximum torque line
The maximum torque momentarily impacts the load when the motor is started.
Beyond this torque, the over-current protection of the driver will cause the motor to stop.
- Short-time operation area
The motor can run for a short time within this torque range at different speeds.
If the operation time is too long, the motor will generate heat, which may cause the motor to stop or burn.
- Rated operating torque line
The rated torque of the motor runs at different speeds, and the motor can run for a long time at this torque.
- Continuous operating area
When the motor rotates at different speeds, it runs continuously in this corresponding zone.
Tips: What are the features of 300W DC worm gear motor?
The worm gear motor can obtain a large transmission ratio by using the worm gear and worm, which is more compact than the staggered-axis helical gear mechanism. The meshing tooth surfaces of the two wheels are in line contact, and its bearing capacity is much higher than that of the staggered-axis helical gear mechanism. The worm drive is equivalent to a screw drive. It is a multi-tooth meshing transmission, so the transmission is stable, the noise is small, and it is self-locking.
When the lead angle of the worm is less than the equivalent friction angle between the meshing gear teeth, the mechanism has self-locking properties and can achieve reverse self-locking, that is, only the worm can drive the worm, but not the worm. When the worm gear is engaged in the transmission, the relative sliding speed between the meshing gear teeth is large, so the friction loss is large and the efficiency is low.
