Starting and regulating resistors

For slip ring motors, which are often used for large power applications, the starting current must be regulated in the starting phase in order to guarantee a smooth start. For this, starting and regulating resistors are used, which are short-circuited little by little as the motor speed increases. For this task, FRIZLEN steel-grid fixed resistors or lamina-type fixed resistors are used, for which multiple partial resistors are integrated into a single device.

Simply ask us, we are always keen to advise you on the optimum configuration of your starting resistor.
