Medical device manufacturers continuously seek ways to decrease component footprints without compromising power. maxon recently introduced the first size of its new ECX Prime motor family, the ECX Prime 6, a small but powerful brushless motor with 4-pole rotors and slotless windings. It has a diameter of only 6 mm and is designed for demanding applications with limited space or where special performance or controller dynamics are required, such as hand prosthetics, surgical tools, or implants.

The ECX Prime 6 o ers speeds of up to 50,000 rpm and continuous torques of up to 0.57 mN-m. The 4-pole technology, already known from larger motors, has been further developed for customized designs and optimized for industrial production in such a small diameter. The motor is made of the best possible materials, including four rotor magnets and the magnetic return of the stator, reducing losses to a minimum and giving the motor a very low speed/torque gradient. This enables stable and dynamic closed-loop control, even when the load increases or fluctuates.

The new motor is available in a High Power (HP) version with Hall or commutation signals. It can be combined with the ENX 6 MAG encoder type and the GPX 6 A gearhead of the standard modular system. For customized versions, the GP 6 S screw drive can be attached via the Flex channel. DW
