permanent magnet motors and series motor
2 types of motors First - AC Second - DC
actually dc motors are of several types in which one of them are 1).brushed 2).brushless ...so the motor present in DVD are the brushless dc motors ...
The different types of motors used in Broan bathroom fans are typically either AC motors or DC motors. AC motors are more common and are powered by alternating current, while DC motors are powered by direct current. Both types of motors are used in Broan fans to provide efficient and reliable operation.
Examples of DC electric motors are the starter in your car and the motor in a DC controlled elevator, to name just two.

Some types of dc (direct current) motor can be used to generate dc, in which case they are often called 'dynamos'. Some alternating current (ac) motors can be used to generate ac, in which case they are called 'alternators', but many types will only work as motors. For instance, a squirrel cage ac motor cannot be used as an alternator.

Photocopiers typically use direct current (DC) motors, particularly brushed DC motors and stepper motors. Brushed DC motors are commonly employed for driving the main components, such as the drum and paper feed mechanisms, due to their simplicity and ease of control. Stepper motors are often used for precise positioning tasks, such as moving the scanning head or adjusting the paper alignment. Both types provide the necessary torque and speed control for efficient operation in photocopying machines.

DC motors are not common in industry. However traction motors are one such main DC motor application. There are many tools, toys, drones, which use DC motors run by batteries.
