Electric motors

General information

 

The drive of the transmission elements of our machines comes from the operation of internal combustion engines or electric motors. In both industrial and residential applications, our machines are mostly equipped with electric motors. The task of electric motors is to produce mechanical (usually rotating) motion from electrical energy. Electric motors can run on direct current or alternating current. In our webshop we sell only AC electric motors.



 

Electric motors can drive transmission belts or roller chain drives. Very often, however, electric motors are geared. These actuators are flanged connected to the electric motors and are designed to change the speed and/or torque of the motor. Certain actuators also change the direction of drive relative to the shaft of the electric motor. In our webshop worm gears are mostly available, the drive of which is perpendicular to the shaft of the electric motor. Helical gearboxes are also available, which are driven parallel to the shaft of the electric motor.

The drive speed of electric motors is constant, since the speed of rotation of the electric motor depends on its winding. This particular speed can be modified with the help of gearboxes or gear ratios. However, if you need a very precise setting or when you need to dynamically intervene in the speed of the electric motor, you will need to use an inverter.

 

What is an asynchronous electric motor?

An asynchronous electric motor is electrical equipment, for the operation of which a magnetic field is created using the so-called stator. The rotational motion occurs on the so-called rotor, which has electromagnetic properties. The connection between the rotor and stator is created by electromagnetic induction, which is why these electric motors are also called induction motors.

What is a gearbox?

A gearbox is a mechanical device that, when connected to the drive motor, changes the drive output by the motor in a way that meets the customer's requirements. The most common task of actuators is to change the engine speed and at the same time vary the engine torque. Actuators can also be used to change the position and direction of the drive. For tasks with different needs, actuators of different designs are produced. In our webshop we offer worm gears and helical gear units to our users.

What is an inverter?

An inverter, also known as an inveter, is a device for controlling the electronic speed of electric motors. In addition to motor speed, the inverter can also check operating parameters, act as a motor protection switch and replace simple PLC tasks such as ramp-up, run-off, direction of rotation.
