The hoisting mechanism employs double winding squirrel-cage pole-changing motor to achieve speed ratio of 1: 6. Shell of motor is made of aluminum alloy by extruding, which has good dissipation. The fan is installed to the end of motor in order to enhance cooling effects. Thermal resistor(or thermal switch)is embedded into winding group of motor to prevent probable motor overheating.
The motor has F insulation level and protection level IP54.
As to the variable-frequency motor of hoisting mechanism, encoder is allowed to install which is ordinarily installed to fan shaft end of Motor.
Technical features:
It has low current for start and large torque
With soft starting and good performance in speed up
Have long service
The technical parameters comply with standards of FEM and HMI
