    Electric Motor Torque

    Taking a sample of 10 electric motors (2Hp, 208/230V, 3600rpm, single phase, capacitor start)and coupling them to a pump we tried to find the Pull/Up Torque of each motor. The motors were designed to have a minimum Pull/Up Torque of 90 oz-ft. All of the motors are from the same batch off the...

    Pull-up Torque Not Consistent

    While testing a line of motors with the required pumps, we noticed that the pull-up torques varied. The motors were designed as 208-230V, 3515 rpm, TENV, 1 Phase. The required minimum pull-up torque was set at 90 oz-ft. This motor was designed with at a minumum of 99 oz-ft of torque. While...
