Synchronous AC Motor for Turntables

31813 Series - Low Speed

image

 

The 31813 series low speed AC Synchronous Motor is 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 length 3mm diameter shaft to aid 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 operating from a 220Vac supply.

Two versions are available, one with a mounting flange the other with a plain body and no flange.

The Body diameter is 51mm and the height is 23.9mm
