Andover, Hants, U.K.— The Unimotor range includes three phase, six or eight pole, permanently excited synchronous motors, exhibiting a sinusoidal back-EMF characteristic. Designed to supply high torque with either low- or high-rotor inertia and minimal cogging torque. Thermal performance is improved by the unique finned motor housing, manufactured in high-strength alloy casting to radiate and convect heat. Commutation and position feedback is provided by an incremental encoder.
