maxon EC-max The maxon EC-max program picks up the ideology of the successful A-max and RE-max motors. The electronically commutated DC motors are based on the same parts platform idea, creating a wide market-oriented range in the modular system with gearheads, sensors and brakes.

Modular construction with gears, sensors and brakes.

The modular EC-motor program with an

impressive price/performance ratio

The motor housing, a simple tube made of stainless steel – non magnetic, rigid, rust-proof.

Non-tension cables can be directed both radially and axially from the motor. Wide range of plug options.

Metallic housing and flange allow good heat dissipation and mechanical stability.

Shaft with no groove guarantees torsional stability and smooth running.

The «heart» is the ironless winding, System maxon®. This means physi-cally dependent – advantages like no detent, high efficiency and excellent regulating dynamics.

High quality, thanks to a process monitored produc-tion on the most modern assembly lines which are, in part, developed by maxon.
