Electrical Motors

Note that most electric motors are designed to run at 50 to 100 of rated load and that maximum efficiency usually is near 75 of rated load for a 1 horsepower hp motor the load should typically be in the range 12 to 1 hp with maximum efficiency at 34 hp typical load ranges acceptable for a shortperiod 20

Servo Or Induction Motor

Nov 06 for example if you need to maintain a constant speed at a large load say for applications greater than 30 or 40hp the induction motor would likely be the better choice this is due to the high costs of producing the large number of permanent magnets needed for such a large motor coupled with the fact that quick accelerations high dynamic

How To Determine The Pole Number Of An Induction Motor

Nov 15 the induction motor will run at a slight less speed due to slip which is what gives the motor its torque for example 55kw 400v 2 pole motor will run at approximately rpm for a four pole machine 60 x 50 2 rpm so the same size motor at 55kw 400v but 4 poles will have a nominal speed of rpm but will run near
