731 inner runner motor

≤ 2 Nm, ≤ 18.000 rpm

The electronically commutated (EC) series 731 motors are designed to be used in battery-driven applications, available in voltages between 12 V and 48 V. In addition to its high efficiency and very low power-to-weight ratio, the EC technology used also enables an exceptionally long lifetime.

The motor is characterised by open construction, which means that it can also be used wherever the impact of the environmental can be harmful. It also provides a very compact design. A wide range of stack heights are available – from 13 mm to 40 mm – which allows flexibility according to customer requirements and installation in end appliances.

The 730 family of EC motors is designed for a power range of 500 to 2,000 W, and the electronics ensure precise regulation and rapid adjustment to various usage requirements.


Nominal power 500–2,000 W
Nominal speed 5,000–18,000 rpm
Nominal torque 0.4–2 Nm
Nominal DC voltage 24 V/36 V/48 V
