Electric motors are electromechanical devices that convert electrical energy into mechanical energy. Electric motors are generally classified as alternating current (AC) motors, direct current (DC) motors, and other motor types. AC motor converts alternating current into mechanical energy. Electric motors are widely used in both discrete and process industries and have incorporated major technological advances, thereby creating a considerable demand among end-users. The development of efficient motors and the need for low power consumption motors are generating a scope of industrial growth for the market. Electric motors are widely used in industrial equipment, ranging from light-duty to heavy-duty applications.

Time of flight (ToF) is a term that denotes various methods used to calculate the time that an object, particle, or wave takes to move through a distance within a medium. A ToF sensor is considered to be an appropriate input device to both stationary and portable computing devices. This sensor is an important component of ToF cameras, which are used in a variety of sectors including automotive, industrial, healthcare, smart advertising, gaming, and entertainment.

Soft starters are devices that are used to protect motors from large current fluctuation or inrush. The current inrush or spikes affect the performance of the medium and low voltage motors. Soft starters help in a smooth start and stop functionality of motors, which in turn increases the motors work life and the overall efficiency of the motors. The starting time for motors depends on the initial load, inertia, and torque. As in most cases, the starting current is higher than the rated operational current of the motors, it becomes essential for having a proper motor control center (MCC) in place, which can provide an adequate supply of current/voltage for the smooth functioning of the motors. There are different techniques used for motor control. Based on the motor power range, application, torque, and speed of the motors, different devices are used to create a smooth stop and start function for the motors.
