2 UNIMOTOR haracteristics Introducing Unimotor Unimotor is a range of brushless servo motors from T ynamics They are three phase, 6 or 8 pole, permanent magnet motors exhibiting a sinusoidal back MF 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 ombined 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) Standard Features Unique 'finned' design - high thermal dissipation ncoder for high precision feedback integral commutation PT thermistors for thermal monitoring and overload protection Low inertia is standard for fast acceleration I mounting flange Key shaft is standard IP65 standard (when connected) - sealed against water spray and dust Low cogging torque & TH (Total Harmonic istortion) Rotor assembly balanced to ISO 1940 grade 6 High standard of mechanical design and precision manufacture - for improved performance and quality Winding insulation is to lass H earing system designed for prolonged motor life Modular construction marked UL and S recognised insulation system Incremental optical encoder 4096 ppr up to 3000 rpm Incremental optical encoder 2048 ppr above 3000 rpm Optional Features bsolute encoder multi-turns Resolver feedback for high temperature applications Sine/osine encoder for high resolution (single and multi-turn) High inertia option Plain shaft (non keyed) Gearbox options rake SLM technology UL recognised motor 2
