Description

maxon DC motors are high-quality DC motors, equipped with powerful permanent magnets. The centerpiece of the motor is the globally patented ironless rotor. Our precious metal brushed combination ensures a high level of consistency of the low contact resistance, even after a long standstill. The motors operate with small startup voltages and extremely low levels of electrical interference.
