22 mm stepper motor

Friday, 17 April, 2009 | Supplied by: ERNTEC Pty Ltd



The two-phase miniature stepper motor with a diameter of 22 mm and a high power-to-volume ratio, the AM 2224, achieves an output of 2.5 W and a peak holding torque of 45 mNm.

There are 3, 6, 12 and 24 V versions available as well as 0.25 and 0.50 A. The motor executes the transmitter control signals with accuracy. This allows an angular step of 15° (even smaller in micro-stepping).

In an open control loop this makes it possible to run rotary speed profiles or build up a positioning control. The use of expensive servo components can usually be avoided. After switching off, the motor maintains its present position.

Like brushless motors, stepper motors do not have any mechanical commutation, so service life is only limited by the bearings.

To also exploit the advantages of this motor technology where more torque is required, the device is available with matching speed reducers, eg, the planetary gearhead series 23/1 increases continuous torque to 0.7 Nm and to 1 Nm in intermittent operation.
