DC Coreless Motors

Motion Control Products have introduced a new range of both Precision and Standard DC coreless motors that have some distinct advantages over orthodox DC motors. These include longer life expectancy, light weight, high acceleration, less vibration, less noise and can operate at very low speeds. Also, DC coreless versions are much more efficient, as there are no iron losses.

The coil is formed as a thin hollow cylinder, rather than the coils being wound around a stack of laminations. The stator with its permanent magnets supplies the magnetic field flux and fits in the hollow centre of the winding. These features provide a much lighter weight motor in comparison to a conventional iron core DC motor. Also, DC coreless versions are much more efficient, as there are no iron losses. In addition, Coreless rotor technology means a smooth running, cog-free operation, with the low inertia rotor providing high dynamic, fast acceleration compared to iron core DC motors.

Motion Control Products offer these coreless motors from 4mm diameter up to 40mm in the standard, motor only format. The precision range is available from 6mm diameter to 32mm diameter. However, they can also be supplied with motor/gearbox combinations and with optional encoders.

Applications that benefit from the advantages of dc coreless technology include:
