WebUnlike DC motors, an AC motor's speed cannot be controlled by modifying the input voltage. Instead, it is necessary to change the AC power supply frequency, which determines the speed of the rotating electromagnetic field in the motor that turns the rotor shaft. A VFD (or Variable Frequency Drive) achieves this by converting the AC power to DC. 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.
