Motor, Reversible, Synchronous, 9904 111 Series, 250 rpm,

The 9904 111 31813 from Allied Motion Premotecis is a low-speed synchronous motor and a development of the standard industrial series specifically designed for use in high-quality record decks which utilise the belt drive principle. Particular attention has been given to the magnetisation of the 24 pole rotor to optimise smooth running.

This, together with the high accuracy of stator pole placement minimises torque ripple and provides low audible noise. The motor which is designed for mounting horizontally with output shaft vertically up is provided with an increased shaft length and a 3 mm diameter to aid the fitment of the drive pulley.

When fitting the drive pulley the shaft rear end should be supported to ensure that the axial load limit is not exceeded. The windings have been specifically designed to facilitate dual voltage operation, a 6.8K Ohm resistor being used in series when operation from a 220 Vac supply is required.
