What is an Electric Motor?

Electric motors convert electrical energy into mechanical energy. You can split motor types into two categories: alternating current (AC) and direct current (DC).

Electric motors keep industrial machinery running. Your electric motor may be used in an industrial robot, air compressors, rolling mills, water pumps, machine tools and more.

Types of Electric Motors

AC Motors –

AC motors are highly flexible. They require low power to start, controlled acceleration, and adjustable speed and torque.

AC motors work directly with variable speed drives and programmable logic controllers. And as these automation parts become more complex, the maintenance of AC motors requires greater technical ability.

Synchronous Motors

Synchronous motors are used for machinery in which speed is required to remain constant. The rotor is synchronised with the frequency of the supply of current.

These types of motors are used in high precision, instrumentation and positioning or processing.

Induction motors

Induction motors can be split into two types: single-phase and three-phase. The former is used in small appliances whilst the latter has industrial uses.

Induction motors are the most common type of AC motor because of their load capacity. Three-phase induction motors are usually in a variable speed drive system.

DC Motors –

DC motors cost less than AC motors and offer faster reaction to different operations. They’re fast at starting, accelerating, reversing and stopping.

DC motors are often used in automotive, lifts and machinery. DC motors are usually split into two types: brushed and brushless.

Brushed Motors

Brushed motors are the most traditional type of motor used. They’re used in simple systems, such as consumer applications and basic industrial automation.

Brushed motors are used in presses, lifts and conveyors.

Brushless motors

Brushless motors are mechanically much simpler than brushed motors.

This type of motor offers speed and positional control. You may use this type of motor to run a pump, compressor, printing and high-speed industrial applications.

Servo Motors –

Servo motors can be AC, DC, brushed or brushless. A servo motor operates in a closed-loop system that uses feedback from an encoder or resolver.

Servo motors are used in applications such as automated manufacturing, CNC machinery and robotics.

Both a stepper motor and a servo motor could be used in a laser cutting machine, for example. The difference is the stepper motor would be a low price, whilst the servo motor would be high performance.

When things go South

Troubleshoot your motor

From magnets to windings, electric motors have countless components. An issue can arise anywhere at any time.

These are some of the most common faults that can occur:

Electrical overload

Low resistance

Overheating or smoke

Dirt & Grease

Moisture damage

Vibration damage

If your electric motor is showing signs of underperformance or complete failure, contact us immediately to have an engineer on-site or to collect the part for free.

Motor rewinding

Motor rewinding generally involves removing the original winding of the motor’s stator or armature and replacing them with new coils made from wire.

Your electric motor may need rewinding if it doesn’t turn on, emits excessive noise and vibration, shooting electric sparks or the carbon brushes are wearing out more frequently.

If you know you need motor rewinding or want to learn more, contact us today.

Get up and running again

Your electric motor plays a vital role in your plant’s running. They can be costly to replace, but easier to repair.

Kontroltek will collect and quote you for free. The Motor Department will disassemble, fault find, repair, balanced, and reassembled before return within 10 days.

Our specialists will also clean and test your electric motor in a setting the same or similar to your workplace.
