PTC thermistor

Accessories for engines and transmissions

To complete your motor, you can choose from our wide range of accessories. Here you will find, for example, suitable torque arms, twin shafts, standstill heaters, motor shafts, motor flanges, temperature sensors, etc. for your drive.

Electronic brake devices

Electronic brakes are used to decelerate squirrel-cage asynchronous motors and single-phase AC capacitor motors within 10 seconds of being switched off. Brake switches for external mounting are available for 1.1 kW, 1.5 kW, 2.2 kW, 3 kW, 4 kW, 5.5 kW, and 7.5 kW motors.

PTC thermistor/thermistor protection

The drives offered here are mostly prepared for temperature monitoring with PTC thermistors. To use this monitoring, you will need the corresponding PTC release device.

The design and the terminal box

The motor design is variable upon request. Even with heavy-duty AC motors, from 4 to 500 kW, the motor feet can be reconfigured. This allows a B3 foot-mounted motor to be converted into a B5 flange-mounted motor, or into a B3/B5 foot/flange motor combination. A further advantage is the ability to reconfigure the drive for terminal box configurations: top, left, right, or even bottom.
