Accessories for motors and gearboxes

Here you have the possibility to make use of our great choice of accessories to make your motor complete. You will find here, for example, the suitable torque support, double shaft, heating during stoppage, motor shaft, motor flange, thermal sensor, etc., for you drive system.


Electronic brake units

Electronic brakes are used to decelerate asynchronous motors with squirrel-cage rotor and 1PH AC capacitor start motors so that motion is stopped within 10 seconds after the motor is turned off. Brake switches are available for external installation in 1.1kW, 1.5kW, 2.2kW, 3kW. 4kW, 5.5kW and 7.5kW motors.


Protection by PTC thermistor

Most of the drives offered here are designed and prepared for temperature monitoring using PTC sensors. To make use of this monitoring function, you need the applicable PTC thermistor triggering device.


Construction type and terminal box

If desired, the construction type of the motors is variable.  Even for AC motors in heavy design, i.e. from 4 kW to 500 kW, the feet of the motor can be modified. Hence, a B3 foot motor can also be converted to a B5 flange motor or to a B4/B5 foot/flange motor. Another advantage is that the drive system can be modified towards a system with terminal box at the top, on the left side, on the right side or even at the bottom.


AC motors of special designs

Here you see a selection of miscellaneous electric motor designs. These are, for example, electric motors / geared motors with:
- variable speed drive (inverter) mounted on the motor
- external fan
- different voltages
- different frequencies
- degree of protection of IP54, IP55, IP65, IP66
- UL/CSA with certificate
- marine grade steel body
- class of isolation H
- protection roof on the fan hood
- insulated ball bearings
- cable outlet
- special paint
- PTC resistor temperature sensor 
- bimetal
- PTC thermistor
- temperature sensor such as PT 100
- bearing temperature monitoring
- heating during stoppage
- terminal box on the left side, right side, topside
- special flange
- special shaft
- second shaft end
- non-oxidizing aluminium fan
- non-oxidizing screws (D 086 DMA)
- rotary encoder
- tachogenerator
- incremental encoder
- NU bearing / fixed bearing
- prestressed bearing
- re-lubrication unit
- particular balancing quality
- motor switch mounted on the motor
