What is an Electric Motor? Types of Electric Motors | CM Industry Supply Automation

 

For converting electrical energy into mechanical energy we generally use an electric motor that generally refers to an electric machine. The majority of electric motors work through the interaction between the magnetic field of the motor and electric current in a wire winding. This interaction creates a force in the form of torque, which is applied to the shaft of the motor.

DC (Direct current (DC) sources like batteries or rectifiers or AC (alternating current) sources like inverters, power grids, or electric generators generally powered electric motors.

Motors are the main reason behind the new technologies we are enjoying today.

Electric motors are generally found in fans, air conditioning, cars, power tools, trains, disk drives, household appliances, and much more. Even we found some small motors in electric watches.

Types of Electric Motors

Nowadays, electric motors become more miscellaneous and adaptable. When we plan a motion control system, we need to make the right choice of motor. The motor should align with the point and complete the performance aims of the system. Fortunately, there is a motor design appropriate for any conceivable reason.

Here are some of the most general electric motors nowadays include:

DC Brushed Motors

When we talk about a DC brushed motor, its current flow is determined by the brush orientation on the stator. In some of the DC Brushed motors models, the orientation of brush compared with the rotor bar segments is important as an alternative. Its most important thing is the commutator.

AC Brushless Motors

In motion control, AC brushless motors are very popular. AC Brushless Motors use rotating magnetic field induction, made in the stator, to rotate both the rotor and stator at a synchronous rate. AC Brushless Motors relies on unending electromagnets to function.

DC Brushless Motors

DC brushless motors offer higher performance in a lesser space as compared to the DC brushed motors. In addition, they are smaller as compared to the AC models. An embedded controller is employed for facilitating work in the absence of a commutator or slip ring.

Direct Drive

Direct drive refers to a high-efficiency, low-wear machinery execution that replaces usual Lenze servo motors and their associated transmissions. Besides being far simpler to maintain over a longer period, Direct drive motors speed up more quickly.

Linear Motors

Linear Motors feature a motor and unrolled stator that produces a linear force along the length of a device. Contrary to cylindrical models, linear motors have a flat active section that features two ends. They are normally faster and more precise as compared to rotatory motors.

Servo Motors

Servo motors are any motor joined with a feedback sensor to ease positioning; therefore, servo motors are the robotics backbone. Mutually linear actuators and rotary are employed. Brushless AC motors superseded low-cost brushed DC motors for high-performance applications.

Stepper Motors

Stepper motors employ an internal rotor, automatically control by outer magnets. The rotors are generally built by soft metal or permanent magnets. The rotor teeth generally align with the magnetic field due to energizing of winding. This permits them to shift from point to point in set increments.

Before work started on any new system, imagine cautiously the challenging properties of the diverse electric motors. The choice of the right electric motors is important to give any project a better start.
