How to slow down ac motor

WebOct 22, 2024 · The reduced load torque at lower speeds helps to keep the motor from overheating. Overheating can be somewhat predicted by measured current vs. the motor's rated current. Measuring the surface temperature of the motor is also somewhat useful. Motor shaft temperature could give some indication of rotor temperature. WebOnly way to change the motor speed is by varying the AC freq. You'll do better with pulleys with your current motor, or switching to a universal motor. This. Using a system of two different sized pulleys connected with a fan belt is your best bet. A smaller motor pulley and larger table pulley setup is what is needed.

How can I slow down a 240V AC motor used for an exhaust fan?

WebJun 21, 2024 · For a 3-phase AC motor with an input voltage of 220VAC, 60 Hz, the motor's synchronous speed (RPM) = 120 x 60 / 4 = 1800 RPM. Synchronous speed is essentially no load speed with the slip. Since applying a rated load would slow down the motor to its rated speed, the difference between rated speed and synchronous speed is the existence of the ...
