How are dc motors generally classified
WebDC Motor. A DC motor is an electrical machine that converts electrical energy into mechanical energy. In a DC motor, the input electrical energy is the direct current which is transformed into the mechanical rotation. In this session, let us know what is a DC motor, types of DC motor and their applications. Table of Contents: WebGenerally, the DC machines are used in supplying excitation of an alternator and it is also used in many applications like welding process, variable-speed motor drives and electrolytic and electroplating process. Small DC machines are used as a control device such as speed sensing, positioning, and tracking.
