Types of Special Motor – Classification of Electric Motor – Types of electrical Motor


The motor or an electric motor is a device
that has brought about one of the biggest advancements in the fields of engineering
and technology, ever since the invention of electricity. A motor is an electro-mechanical device that
converts electrical energy to mechanical energy. The primary classification of Electrical motor
is mainly three types. 1. DC Motor, 2. AC Motor, 3. Special Motor. DC motor and AC Motor classifications, we
will describe in another video, and this video link in Description below. Special motor are four types. 1. Stepper Motor. 2. Servo Motor. 3. Universal Motor. 4. DC Brushless Motor. Stepper Motor. Stepper motors are DC motors that move in
discrete steps. They have multiple coils that are organized
in groups called “phases”. By energizing each phase in sequence, the
motor will rotate, one step at a time. With a computer controlled stepping you can
achieve very precise positioning and speed control. Servo Motor. A servomotor is a rotary actuator or linear
actuator that allows for precise control of angular or linear position, velocity and acceleration. It consists of a suitable motor coupled to
a sensor for position feedback. Universal Motor:
The universal motor is so named because it is a type of electric motor that can operate
on AC or DC power. It is a commutated series-wound motor where
the stator’s field coils are connected in series with the rotor windings through a commentator. It is often referred to as an AC series motor. The universal motor is very similar to a DC
series motor in construction, but is modified slightly to allow the motor to operate properly
on AC power. DC Brushless Motor:
Brushless DC electric motor also known as electronically commutated motors are synchronous
motors that are powered by a DC electric source via an integrated inverter or switching power
supply, which produces an AC electric signal to drive the motor. In this context, AC current does not imply
a sinusoidal waveform, but rather a bi-directional current with no restriction on waveform. Additional sensors and electronics control
the inverter output amplitude and waveform and frequency. Dear sir, Thanks for watching the video. For more update please subscribes our channel
