Which of the following is not a function of motor control?

In the context of motor control, the primary functions are focused on the operational aspects of starting, stopping, and protecting the motor during its operation. Starting the motor refers to the initiation of its motion, while stopping the motor involves safely halting its operation. Overcurrent protection is crucial for preventing damage to the motor due to excessive current, which can occur during starting or due to a fault condition.

Enhancing motor speed, however, is not typically classified as a function of motor control itself. While motor control systems can influence speed through various methods such as variable frequency drives (VFDs) or controllers that adjust voltage and current, the fundamental role of motor control is to manage the motor's operation rather than specifically enhance its speed. Speed enhancement is more about the design and capabilities of the motor itself and the control technology used, rather than the core function of basic motor control.
