Motor Overview

The J series medium-sized motors are designed to drive various types of machinery, including:

Fans,
Compressors,
Pumps,
Crushers,
Ball mills,
Cutting machine tools,
Transport machinery, and other equipment.

They are suitable for use in:

Coal mines,
Machinery industries,
Power plants, and
Various industrial and mining enterprises as prime movers.
The JR series is a wound rotor three-phase asynchronous motor.
It complies with the technical conditions specified in the JB564-64 standards.

Starting Characteristics

JS series motors:

Allow full-voltage direct starting.
Initial starting torque and current ratios to rated values are shown in Table 3.
If full-voltage starting is restricted by the power grid, reduced-voltage starting can be used. However, the starting torque will decrease proportionally to the square of the starting voltage.
