Asynchronous Induction Motor with Fan Cooling

We offer the best quality Electric motor with the most competitive prices.

Electric motor is a specific type of electric machine which has characteristic of soft machinery and wide range speed control. It has the advantages of slow-speed of revolution, high torque, strong overload capacity, fast response, features good linearity and small torque variation, etc. The power output of electric motor axle is not constant, but constant torque. The characteristics of electric motor in this series apply to convolution, unreeling, stalling, speed regulating and other than utility. It is widely used in spinning, electric wire and cable, metal-processing industry, paper industry, rubber industry, plastics industry and mechanical industry.

Principle:
When load increase, the speed of electric motor can slowdown automatically. However the output torque will increase to keep balance with load. When the loacked-rotor torque of electric motor is high and locked-rotor current is small that can bear stalling. As rotor has higher electrical resistance and big loss that hot is serious, especial in low speed working. So the back-end of electric motor has individual axial flow or centrifugal fan (except output torque less than seat NO100). It is used for forced draught cooling. Electric motor with control gear can use for control gear and the speed regulationg range can reach 1: 4, relative speed variation is less than equal to 10%.

Electric motor rated voltage: 380V
Rated frequency: 50Hz
Altitude: No more than 1000m
Protective level: H80 ~ H180 for IP21
H63 ~ H160 for IP44

YLJ series three-phase asynchronous motor torque applicable papermaking, wires and cables, rubber, plastic, textile and metal materials processing departments for winding, uncoiling, stall and speed-varying units. Also can use its characters of stall, reverse, and is used for frequently, reverse device or other similar action of all kinds of machines. Like extrusion, clamping, opening, pull, screw rotation speed, torque etc randomly occasion.
