JS Series Squirrel Cage Three Phase Asynchronous Motor

Brief Introduction

JS series motor is squirrel cage rotor three-phase asynchronous motor. It meets the standard of JB 563-64 / IEC technical requirements. It is permitted to be started on full voltage directly. The basic mounting mode of this type is horizontal installation with mounting foot. It should be connected with the driven machine by coupler device. JS motor adopted a double - sided radial ventilation system and antifriction bearing. By the side of shaft extension end, the terminal box is on the right seen from the DE end. It can be produced into double-shaft extension.

It is good performance, such as high safety, compact design, low noise, little vibration, big breakaway torque, reliable operation, stable running and convenient maintenance.

It can be fit for common working environment and machinery without special requirement, such as ventilator, compressor, water pump, crusher, ball mill, stock-removing machine, transport machine and other machinery.

It also can be prime drive force of industries like coal mine, mechanical industry, power station and different kinds of manufacturing and mining industries.
