Two new brushless flat-dc micromotors provide diameters of 15 and 26 mm. The precious-metal commutated micromotors have nominal voltages of 6 or 12 V. The 15-mm-diameter model provides a 0.6-mNm continuous output torque, while the 26-mm-diameter version offers 3.8 mNm. The output torque can be increased up to 30 or 100 mNm with gearmotor versions of the new drives.
Electronic commutation is based on three digital Hall sensors. The cog-free motors feature smooth operation, high efficiency, and long operational life. The gearmotor versions come with reduction ratios of 6 to 324:1 (Series 15…B) or 8 to 1257:1 (Series 26…B). The 26-mm motor has an optional integrated speed controller.
The micro motors are suitable for portable devices or continuous-duty operations such as those in laboratory and medical-device applications.
