mechanisms in very harsh working conditions such as construction site or open pit quarry.


With introduction of spline drive shaft, it has good mechanical bearing capacity;
The motor is a variable-frequency motor featuring a wide range of speed regulation, high efficiency, small starting current, big starting torque and overload ability;
A thermal protection component is buried into the in winding, making motor more safer and reliable;
Excellent dedicated variable-frequency insulation materials are adopted, improving greatly the insulation reliability;
Compact structure, small volume, lightweight, so it can be braked quickly and positioned accurately. It is suitable for frequent starting and braking;
