Name three factors that determine the torque produced by an induction motor.
Given the following experimental data collected, what is the approximate torque of this motor at peak efficiency?
A 7460 W split-phase motor running at 1750 rpm is used to drive a rotary pump. The pump should run continuously at approximately 1175 rpm. The center distance should not exceed 1118 mm. Space limits the diameter of the driven pulley to 292 mm.
Determine:
a. the pulley diameters,
b. the belt size, and
c. the number of belt required.
