Reversible AC Synchronous Motors The 9904 111 series reversible ac synchronous motors provide fixed speed operation and are ideally suited to a wide range of control & instrumentation applications. The units low speed, either 250 or 500 rpm, ensure low mechanical noise and smooth operation when used with additional gearing in low speed drives. The motors may be specified with a wide range of factory fitted gearheads where increased torque and reduced operating speed is required. Gearheads for the 35 & 51 mm options provide a choice of standard ratios with output speed options from 1 rev/second down to 1 rev/hour. while the high torque 56 mm model may be fitted with gearheads providing speeds down to 30 revs/hour. Reversible ac synchronous motor dimensions The motors are either provided with leads ( Form 1 A ) or solder terminals ( Forms 1B & 1C) as shown below: L7 L1 L2 D4 L5 T1 D2 D1 T2 L4 D3 L6 L8 L3 T1 Form 1 Form 1A Form 1B Form 1C motor type form dimensions mm 9904-111- D1 D2 D3 D4 L1 L2 L3 L4 L5 L6 L7 L8 T1 T2 32 series 1 A 35 2 10 3.2 21.5 8.8 50 42 1.2 0.8 2.2 175 N/A N/A 31- x11 1 A 51 1.8 10 3.5 25 8.2 70.5 60.2 1.5 1.0 3 175 N/A N/A 31- x01 1 A 51 3 10 3.5 25 8.2 70.5 60.2 1.5 1.0 3 175 N/A N/A 31- x14 1 B 51 1.8 10 3.5 25 8.2 70.5 60.2 1.5 1.0 3 N/A 38.5 18.3 31- x04 1 B 51 3 10 3.5 25 8.2 70.5 60.2 1.5 1.0 3 N/A 38.5 18.3 35 series 1 C 56.3 3 12 4.4 33.5 8.2 76.5 66 1.5 1.5 3.8 N/A 37.1 20 36 series 1 C 56.3 3 12 4.4 33.5 8.2 76.5 66 1.5 1.5 3.8 N/A 37.1 20 Reversible AC Synchronous Motor Performance motor type Supply Voltage Speed Working Torque Current Phasing Capacitor Mass coils connected in 50Hz coils connected in coils connected in Parallel Series Parallel Series Parallel Series rpm m A Vac Vac Ncm Ncm grams F F 9904 111 32 311 110 220 250 0.4 0.7 8 0.1 0.22 80 9904 111 32 511 48 24 35 2.2 4.7 9904 111 31 111 220 16 0.1 9904 111 31 104 250 2.0 160 9904 111 31 311 110 30 0.39 9904 111 31 304 9904 111 31 511 24 150 8 9904 111 31 504 9904 111 35 104 220 250 3.3 15 0.12 300 9904 111 35 504 24 140 10 9904 111 36 104 220 500 3.3 30 0.22 300 9904 111 36 504 24 280 18 note** The above motors are rated for continuous operation. except the 36 series which is rated for a 50% duty cycle The 250 rpm motors may be used on a 60Hz supply to provide 300 rpm using different phasing capacitors Mclennan Servo Supplies Ltd.

The motors run at a fixed speed synchronous with mains frequency, at any torque up to the motors operating limit. They are therefore ideal for high accuracy fixed speed drives. The motors will accelerate to operating speed in typically Red Blue 100 msecs. and will stop within typically 60 degrees once power is removed, depending on the load inertia. They are therefore suitable for positioning applications where the high accuracy of a stepper motor, for example, is not required If starting problems are experienced in applications featuring CCW low friction torque it is usually because the load inertia is too Grey Grey high. In these cases a coupling with some compliance often helps to overcome this problem. When a gearhead is used Capacitor CW for reduced speed operation the reflected load inertia at the motor is reduced by the square of the gear ratio.
