Brushless AC Servo Motors
1 to 73 Nm

UNIMOTOR
Suitable for use with M'Ax and Unidrive V3 Servo


Unimotor is a new range of brushless AC servo motors from Control Techniques which are available as three phase, 6 or 8 pole, permanent magnet motors exhibiting a sinusoidal back EMF characteristic. The motors supply high torque with either low or high rotor inertia and minimal cogging torque.

The unique 'finned' motor housing is a high-strength aluminium alloy casting, that improves heat dissipation by conduction, radiation and convection. The single-piece integral construction
permits accurate bearing to housing alignment and maintains air gap concentricity.
This arrangement optimises torque output and reduces cogging torque. The compact design gives increased torsional stiffness. Laminations and coils are optimised both for high efficiency and to provide low harmonic distortion in the airgap flux. Combined with the high energy magnets, and a choice of rotor inertia, these features provide superb dynamic performance to suit all requirements.
