What are the 4 main motor types?
There are four main brushed motor types, including:
- Series Motors. The stator is in series or identical with the rotor, causing their field currents to be identical. …
- Shunt Motors. …
- Cumulative Compound Motors. …
- PMDC Motors (Permanent Magnet).
What is the most common DC motor?
The two most common types of DC motors are known as brush DC and brushless DC (BLDC). Although the underlying physics is the same, their construction, performance characteristics, and means of control are very different.
What are the two main parts of DC motor?
DC motors include two key components: a stator and an armature. The stator is the stationary part of a motor, while the armature rotates. In a DC motor, the stator provides a rotating magnetic field that drives the armature to rotate.
What are the applications of DC motor?
In portable applications using battery power, DC motors are a natural choice. DC machines are also used in applications where high starting torque and accurate speed control over a wide range are important. Major applications for DC motors are: elevators, steel mills, rolling mills, locomotives, and excavators.
What is simple DC motor?
A simple DC motor uses a stationary set of magnets in the stator, and a coil of wire with a current running through it to generate an electromagnetic field aligned with the centre of the coil. … The commutator allows each armature coil to be energised in turn, creating a steady rotating force (known as torque).
What is the speed of DC motor?
DC controls adjust speed by varying the voltage sent to the motor (this differs from AC motor controls which adjust the line frequency to the motor). Typical no load or synchronous speeds for an AC fractional horsepower motor are 1800 or 3600 rpm, and 1000-5000 rpm for DC fractional hp motors.
