Product details
1. Pure copper wire winding
The rotor is made of pure copper with small resistance and strong conductivity, which enhances the motor torque.
2. All metal gear mechanism
Wear resistance, strong torsion resistance, smooth transmission, compact structure.
3. D font axis
D-shaped shaft, more convenient to install, not easy to slip, save installation time
4. Rare earth magnetic hollow cup motor input
High efficiency, low noise, good sensitivity, long life, energy saving, fast response, etc.
5. Frequent blocking or frequent start-up and reversal are not recommended in the use process, which will greatly reduce the service life.
It is suggested that the gear reducer should be used within 2.0kg.cm of rated load as far as possible, and there is a risk of damage if the gear reducer exceeds 2.0kg.cm.
