Electric Motors

Electric motor is the name given to a device that converts electrical energy into mechanical energy. Each electric motor consists of two main parts, one fixed (stator) and the other rotating around itself (rotor). These main parts are electric current-conducting parts (such as coils), magnetic flux-transmitting parts and construction parts (such as screws and bearings), etc. It consists of different parts.

Basically, electric motors are divided into alternating current electric motors and direct current electric motors.

Alternating current motors can be divided into two groups: Asynchronous motors (induction motors) and synchronous motors. The basic operating principle of these motors is based on the drift of a mass made of magnetic sheets with the help of a rotating electromagnetic field.

Direct current motors are designed to operate with direct electric current. The most common types are brushed and brushless types.

The standard definitions, previously made in the form of EFF, were published by the International Electrotechnical Commission (IEC) and became the European norm with CENELEC in 2009; In 2010, with the TS EN 60034-30 standard adopted by the TSE, the electric motor efficiency classes were defined as IE1, IE2, IE3 and IE4. According to this new definition, IE1 is defined as standard efficiency, IE2 high efficiency, IE3 very high efficiency and IE4 super very high efficiency motors. For exceptions to the 60034-30-1 standard, the main; motors designed for multiple speeds; mechanical converter motors; Engines that are fully integrated into the machine, such as pump, fan, compressor; There are submersible motors, ex-proof and brake motors designed to operate by completely immersing them in liquid.
