Introducing Unimotor
Unimotor is a new range of brushless AC servo
motors from Control Techniques. They are 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.
The integral housing and front flange design
increases thermal dissipation and improves sealing
(IP65 standard, when mounted and connected).
