  • Operating Range

    Continuous operation range
    Short term operation range


maxon DC motors are high-quality 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.
