Electric motors are electrical machines engineered to convert electrical energy into mechanical energy. Generally, electric motors interact with their own magnetic fields and the electric current is carried by a wire to generate force, which they leverage as torque to drive the motor’s shaft.
Types of electric motors
There are different types of electric motors available. The most common types include:
AC/DC motors come either in brush or brushless varieties and can be synchronous and asynchronous respectively. The brushless varieties are faster than the brushed ones.
AC/DC Geared Motors
These types of electric motors are specifically suitable where RPM output is required.
Servo motors are widely used where accurate control across positions, acceleration, and velocity is needed to be established of angular or linear position.
Accessories of electric motors
Accessories for electric motors assist in their operation and enhance their performance to improve efficiency. Some of the commonly used accessories for electric motors are:
Soft starts: This reduces the torque and lengthens lifespan.
Motor starters: This accessory controls the total amount of electrical power delivered during startup.
EMI filters: This minimises electromagnetic interference.
Inverters: Inverters are electric motor accessories that can adjust the speed of the motor and control the AC motor speed in electro-mechanical drive systems.
Motor protectors: These are responsible for protecting the motors against any potential damage and enhance durability.
