High Performance Crusher Motor - Regal Beloit

A Blue Chip Series® XRI® Crusher Duty motor with NEMA Premium ® efficiencies was chosen because the cost of operation during its life accounts for 90% of the total purchase cost of the motor and an ultra-high efficiency motor reduces the pit's operating cost. More importantly, the higher starting and breakdown torques, integrally cast frame ...


How to determine the pole number of an induction motor ...

The induction motor will run at a slight less speed due to "slip" which is what gives the motor its torque. For example 5.5kW, 400v, 2 pole motor will run at approximately 2880 rpm. For a four pole machine, 60 x 50 / 2 = 1500 rpm so the same size motor at 5.5kW, 400v but 4 poles will have a nominal speed of 1500rpm but will run near 1455 rpm.

No Load Test of Induction Motor - your electrical guide. The no load test of 3 phase induction motor is performed on induction motor when it is running without load. This test tells us the magnitude of constant losses occurring in the motor. The set up for no load test of induction motor is shown in the figure.


Motor torque, load torque and selection of motors

requirement when the load characteristics are known, or as in NEMA class C, or as the manufacturer's own practice, when the starting torque requirement exceeds 150% of the full-load torque (FLT). The likely applications for a high starting torque may be induced-draught fans, blowers, coal crushers, mill motors and coal conveyor motors.

Applications of 3-Phase Induction Motors

The slip ring induction motors are also used for loads which require a gradual build-up of load. They are used for loads that requires speed control. Typical applications of wound rotor or slip ring induction motors are crushers, plunger pumps, cranes & hoists, elevators, compressors and conveyors.

Motor Sizing Calculations - Oriental Motor U.S.A. Corp.

Standard AC Motors The speed of Induction Motors and Reversible Motors vary with the size of the load torque. So, the selection should be made between the rated speed and the synchronous speed. There can be a difference of continuous and short-term ratings, due to the difference in motor specifications, despite the fact that two motors have the ...


How to Size Motors for Load, Horsepower, Motor Horsepower ...

If the motor load varies 90 % or less from full load for extensive amounts of time, the application may be right for a variable speed drive and, thus, significant savings. For instance, if motor horsepower requirements can be reduced with a variable speed drive to decrease motor speed to 90 % of the motor's full rated speed, then energy consumption is reduced to 73 % of what …
