HOW A MOTOR WORKS?

DEFINITION:

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.

HOW IT WORKS:

The basic idea of an electric motor is really simple: you put electricity into it at one end and an axle (metal rod) rotates at the other end giving you the power to drive a machine of some kind. ... When an electric current starts to creep along a wire, it creates a magnetic field all around it.

TYPES:

Some of the most common electric motors used today include:

AC Brushless Motors. 

DC Brushed Motors.  

DC Brushless Motors. 

Direct Drive. 

Linear Motors. 

Servo Motors. 

Stepper Motors.

BRIEF:

AC Brushless Motors

AC brushless motors use the induction of a rotating magnetic field in the stator to turn the rotor and stator at the same rate. Like DC motors, these are permanent-magnet synchronous motors, or PMSMs, that rely upon magnets built into the rotor.

DIRECT DRIVE MOTOR:

A direct drive mechanism is one that uses the torque coming from a motor without any reductions. Direct drive mechanisms can be categorized in groups Torque motor mechanisms. Output shaft is driven either by brush torque motor or brushless torque motor. The brushless torque motor

STEPPER MOTORS:

Commercially, stepper motors are used in floppy disk drives, flatbed scanners, computer printers, plotters, slot machines, image scanners, compact disc drives, intelligent lighting, camera lenses, CNC machines and, more recently, in 3D printers.

SERVO MOTORS:

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.

BRUSHLESS DC MOTOR:

A brushless DC motor (also known as a BLDC motor or BL motor) is an electronically commuted DC motor which does not have brushes. The controller provides pulses of current to the motor windings which control the speed and torque of the synchronous motor.

LINEAR MOTOR:

     

A linear motor is an electric motor that has had its stator and rotor "unrolled" thus instead of producing a torque (rotation) it produces a linear force along its length. However, linear motors are not necessarily straight.

BRUSHED DC MOTOR:

A brushed DC electric motor is an internally commutated electric motor designed to be run from a direct current power source.
