Available ex stock.

See M 11 Price List for selection information.

The modular built-on accessories concept, with the

pulse generator, separately driven fan and brake, does

away with special versions. This patented mounting

technique allows the standard motors to be installed

quickly, easily and economically for all applications.

The modular built-on accessories concept cuts the

costs for installation, commissioning and stocking of

spare parts.

Frame sizes 56 to 315 LOutput range 0.06 to 160 kW


Significant improvement in efficiency as

compared with the basic design.

Considerable savings, yet low investment costs.

Additional suitable:

For the American market: efficiency

to EPACT.

Class F

COMBIMASTER motors are the ideal solution for

variable-speed drives:

short installation time

retrofittable for existing set speed usages

maintenance friendly because of the adaption

concept (motor and inverter can be easily

separated)

EMC-compatible (no cable between motor and

inverter reduces spurious radiation in the plant).

Frame sizes 63 to 450
