Which voltages are commonly used in motor control circuits?

In motor control circuits, the voltages typically used for control purposes are 120V, 240V, and 24V. These voltages serve different purposes within the context of motor control systems.

120V and 240V are often employed as line voltages for larger industrial motors and equipment. They facilitate the direct power needed to operate heavy loads efficiently. In contrast, 24V is a common control voltage used for low-voltage control circuits, which enhances safety by minimizing shock hazards and is widely adopted in control devices like relays and contactors.

This combination addresses the variety of applications in motor control, ensuring compatibility with both residential and industrial settings. By using these standard voltages, technicians and engineers can ensure reliable functionality and easier integration with existing systems while adhering to safety regulations.
