250 rpm Synchronous Motor
The 31813 series low speed synchronous motor is a development of the
standard industrial series specifically designed for use in high quality
record decks that 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 fitting of the drive pulley. When fitting the drive pulley
the shaft rear end should be supported to ensure that the axial load
limitation 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.
