A variable-frequency drive is a device used in a drive system consisting of the following three main sub-systems: AC motor, main drive controller assembly, and drive/operator interface. The width of the pulses determines the position of the output shaft. Simply put, a variable speed motor is a motor that has a variable frequency drive or similar technology installed to control motor speed and torque. The motor "slip," normally close to zero, will increase as reduced power is supplied to the motor, and the motor poles don't receive enough power to produce the force necessary to keep up their normal speed. Defective products, by contrast, will fail when nominal stress is applied to the defect site. Protect your brand and your customers' bottom lines by working with a long-established leader in component sourcing: Telco. 99. Nominal products will withstand nominal stress, so they will last their entire design lifetime provided that they are not exposed to stresses exceeding the specified levels. Typically a Variable Speed Drive (VSD) is a system that uses an external signal to control the rotational speed and torque of an AC induction motor by adjusting the frequency of the power supplied to the motor. For applications where variable speeds are necessary, typically an AC motor with an Inverter or brush motors are used.
