High performance drive in a small package

Maxon's EC 4 brushless DC motor is said to be the smallest micromotor to come from the Swiss manufacturer, with a diameter of 4mm. It is available in 12.4, 17.4, 21 and 24.4mm lengths, with power ratings of 0.5 and 1W. Equipped with an ironless maxon winding, the EC 4 has a robust design, high power density and is claimed to be energy efficient.


Combined with the GP 4 planetary gearhead, the EC 4 becomes a compact drive for use in micropumps, analytic and diagnostic devices, and laboratory robots. Precise and reliable, it can adjust lenses, dispense fluids, or position sensing devices.

All units meet the ISO 13485 medical standard, which makes this maxon micro drive a suitable choice for applications in medical technology.
