24.4 x 30.8mm inner rotor brushless motor with 2 poles, no carbon brush wear, low noise running and a service life of up to 20,000 hours.
Low noise runningUp to 20000 hoursOptional built-in MCU driverThis model replaces the brushed 370 platform. Because commutation is electronic, there are no carbon brushes and no brush dust, so running noise stays stable over the whole service life instead of rising as brushes wear. A balanced rotor, precision shaft fit and oil-impregnated bearings keep vibration low, which is what allows the 20,000 hour rating in continuous appliance and pump duty.
