Electromagnetic clutches are designed to open and close shaft parts at very high torques, as well as for automatic and remote control of drives. Electromagnetic clutches are made from durable friction materials, they are corrosion protected and require little or no maintenance after installation.
In the industrial industry, the following electromagnetic clutches are used: friction, gear and magnetic. In addition, brake, contactless and contact electromagnetic clutches are widely used. Typical applications include transmissions, automatic gearboxes, auxiliary movements and power feeds, and other systems that require disengagement of parts on the fly without causing shock, typically in a cyclical manner.
Electromagnetic clutches are widely used in the repair of diesel locomotives, metal-cutting machines, used in medical equipment, conveyors, textile machines, electric drives of drawworks, copying equipment, etc. However, electromagnetic clutches in all these mechanisms and devices have far from the same use. For different types of work, it is necessary to choose the correct coupling correctly. When choosing couplings, it is necessary to take into account the operating conditions, including the moments with which the coupling must work, the time and energy of the transition, the level of losses. Custom devices can also be made according to customer requirements.
The main advantages of using electromagnetic clutches are: reduction of the starting current time, the possibility of alternate starting of mechanisms and motors, elimination of slippage and overloads, ensuring smooth operation, elimination of shock loads on motors and mechanisms, as well as many other operational advantages.
However, the main advantage of electromagnetic clutches is the ability to significantly reduce the start-up losses of the electric motor, which is an important aspect for the cyclic operation of the engine. Due to these advantages, the demand for these devices is constantly increasing.
