iron core dc motors

The Premotec Iron core motors have a modular

structure that allows the motor to be integrated

with two gearbox types in ratios from 6 to 729:1.

The use of plastic in these motors minimizes cost

whilst giving high resistance to chemicals and

corrosion. Reliability is maximized by using

internal spark suppression. Metal-geared versions

are available for higher torque versions. Below is a

list of our iron core motor program.


The iron core motor performance is summarized below.
