What Are Common Types Of Motors?
Electric motors are a staple element of countless industries and applications, serving as machines capable of transforming electrical energy into mechanical energy. With a plethora of motor types, sizes, and ratings, finding the correct fit for a particular need or use can be daunting at times. To find a best fit for a specific application, it can be highly beneficial to have a general understanding of some of the most common electrical motor types, their functionalities, and uses.
DC Series Motor
The DC series motor is a type of electric motor that utilizes direct current. In such motors, the rotor windings and armature are connected in series with a shared power source. Motor speed is typically dependent upon load torque and armature current, and such devices are known for providing a high starting torque. With their capabilities, DC series motor types are commonly used for starting high inertia loads such as are seen in elevators, trains, and automobiles.
Synchronous Motor
Synchronous motors are one of the most common three-phase motor types, capable of rotating an electromagnet at the same speed of the rotating magnetic field to achieve synchronous operations. While not self starting, such motors can be highly beneficial for their ability to operate as a constant speed motor regardless of load condition. For their applications, synchronous motors are commonly found within automation and robotics, providing high levels of accuracy.
Induction Motor
The induction motor is another widely used AC motor type, commonly referred to as an asynchronous motor. To transform electrical energy into mechanical energy, such motors utilize electromagnetic induction. Induction motors come in two types depending upon their rotor, those of which are wound types and squirrel-cage types. As a simple and reliable motor, such devices may be found within refrigerators, washing machines, pumps, winders, conveyors, and much more.
Brushless DC Motor
Brushless DC motors are a type of synchronous motor that utilizes a direct current power supply for their operations. Rather than using a mechanical commutator, brushless DC motors take advantage of an electronic closed loop controller that is capable of adjusting the phase and amplitude of current pulses for the means of managing the motor's speed and torque. With reduced energy use, compact construction, long service lives, and other benefits, such motors are commonly used as home appliance motors, industrial engineering motors, aircraft motor devices, and much more.
Stepper Motor
The stepper motor is a type of brushless DC motor that is capable of dividing a full rotation into equal steps. While maintaining torque and speed, the stepper motor is capable of moving and holding the positions of rotation without the need for a controller or a position sensor. The stepper motor can come in a variety of types, the main three being the permanent magnet stepper, variable reluctance stepper, and hybrid synchronous stepper. Stepper motors are commonly found within precision positioning equipment, computer printers, camera lenses, 3D printers, and other equipment.
Universal Motor
The universal motor is true to its name, acting as a special device that may work on AC and DC power. Such motors also utilize an electromagnet as their stator, and the stator’s field coils are designed in series with the rotor windings with the use of a commutator. While having a similar design to DC series motors, adjustments are made to allow the device to efficiently use AC power. As a more flexible motor option, universal motors are often used for domestic appliances and rail traction applications. They can also serve as a type of aircraft motor, generally implemented for the starting process of a combustion engine.
