Motor Base Type MW10

Motor Base Type MW10

Motor Base
MW 10

The MW-10 is made for belt drives with motors from 37 kW to 200 kW output.

Depending on the specitications of the drive system, the motor base can be steplessly adjusted via a single, maintenance-free pretensioning unit equipped with axial ball bearings for smooth operation.

Indentical mounting holes on the motor and base plate are suitable for all motor sizes, from IEC 2058S – IEC 315M and NEMA 404T – NEMA 4477.

This and the compact design allow easy installation even in existing systems with limited space. The use of the MW-10 motor base guarantees optimum belt tension at all times thanks to it self-regulating function. This means maximum efficiency and minimum maintenance!
