The Basics of Motor Selection

Speed and torque represent the output that will be required to power the application and will affect the size of the motor A speed and torque rating is the starting point in selecting a motor once the initial constraints are determined Size can also be impacted by minimum requirements for starting or stall torques and duty cycle.

Why a 1800RPM instead of a 3600RPM motor CPE Systems Inc.

03 06 2016  When the 1HP pump is operating in the optimal range approx 2700 rpm the 3600 RPM motor is still be producing 1.5 ft/lbs of torque while the 1800 RPM motor s output will be somewhere between 1.5 and 3 ft/lbs Finally when the pump is operating at the top speed of 3600 RPM both motors would be putting out the same 1.5 ft lbs of torque.
