Air-cooled starters or motor starters are built with fixed resistors of the 3PR grid type. These grids are made of cast iron and have a very high overload capacity compared to stainless steel grids. The resistors are inserted into the rotor circuit of a wound-rotor asynchronous motor and then short-circuited from the rotor in sequence by contactors.
Step resistor starters are particularly suitable for conveyor belt drives where multiple motors drive a belt because of the precise resistor control. Oil-cooled 3PA starters are also capable of operating at the lowest temperatures without additional heating.
GINO AG offers customized air-cooled motor starters for installation in e-houses or as individual units for outdoor installation. In addition to resistor cabinets or resistor racks, we also design and manufacture protective cabinets and PLC control cabinets
