Maxon is expanding its range of high-precision drives with the addition of five flat motors, ranging in diameter from 6 to 90 mm and a nominal operating range of 30 mW up to 90 W. Brushless DC motors, known as electronically commutated drives, have an almost unlimited service life. The motors are designed as external rotors, with minimized operating noise. As a result, the rotating rotor shell encloses the fixed stator. A ring-shaped, multipole permanent magnet sits in the shell and the stator is also multipole. The magnetic rotary field needed for the motion is produced in the windings. The operating temperature range is –40 to +100 °C. In low-output range, the drives are fitted with flexprint PCBs, but the powerful models (50 and 90 W) are fitted with rigid circuit boards. In this series, two principles are offered: a long and slim version with internal rotors also known as squirrel cage motors, and flat motors also known as pancake models.
