FREQUENCY INVERTERS (THE FREQUENCY INVERTER) AND FREQUENCY-REGULATED DRIVE

Frequency inverters carry out soft star of asynchronous electric motor, and also management of their productivity. Frequency inverters allow to carry out management of the electric motor with a preset value of a nominal and working current.

In the catalog are presented frequency inverters of the most different capacity for performance of any tasks. We cooperate with clients across all Russia, in particular in Rostov-on-Don, Nizhni Novgorod, Ekaterinburg, Novosibirsk, Perm, Chelyabinsk.

 


 

Frequency inverters find the application on large and small-scale productions where is necessary adjustment of speed of rotation of asynchronous electric motors, by change of voltage of the electric motor. To operate speed of rotation of the electric motor probably in wide enough range, carrying out complete control both at start and stop stages, and in the course of equipment work. Thus becomes possible not only to protect the electric motor from overloads, but also considerably to increase term of its service and to save to 60 % energy consumption.

 

Frequency inverters are subdivided into two basic classes: 
  • Frequency inverters with intermediate link a direct current.
  • Frequency converters with a direct connection.
Proceeding from this division the scope of the frequency inverter also is defined. As a rule, the frequency inverter is used in processes where is required constant change of speed of rotation of the electric motor.  This device generates electric power with variable characteristics, as a result  is produced control of electric motors, which transform electrical energy into mechanical energy.
