Understanding Industrial Motors and their Importance
AC Motors
Alternating current (AC) motors are one of the most common types of industrial motors used across various industries. AC motors work on alternating current and have properties such as easy speed control, high starting torque, overload capacity, etc. Some common types of AC motors include induction motors, synchronous motors, and servo motors. Induction motors are the most widely used AC motor due to their simple and robust construction, low cost of maintenance, and ability to start under load. They find applications in equipment requiring continuous speed regulation like assembly lines, pumps, conveyors, etc. Synchronous motors are designed for applications requiring precise speed synchronism like CNC machines.
DC Motors
Direct current (DC) motors operate using direct current power sources like batteries. Some key characteristics of Industrial Motors include high starting torque, ability of speed and torque control, and ability to work in either direction by reversing the current flow. DC motors mainly find usage where variable or reversible speed control is important such as in robotics, fluid couplings, printing machines, elevators, etc.
Common DC motor types include brushed DC motors and brushless DC motors. Brushed DC motors have commutator and brushes to carry current to the rotor. Brushless DC motors have replaced brushes with solid-state electronic switches thereby eliminating brush and commutation problems.
