Fleecaf Posted April 6, 2009 Share Posted April 6, 2009 Hello all, I've got a 5RPM Cassette Rotator which I need to go at 2 1/2 RPM. Is it just a case of fitting an appropriate resistor to its feed? Or am I gonna be fiddling with gears/cogs etc? Many Thanks, Keith. Link to comment Share on other sites More sharing options...
Brian Posted April 6, 2009 Share Posted April 6, 2009 Or am I gonna be fiddling with gears/cogs etc?No, you're going to be swapping the whole gear box. Link to comment Share on other sites More sharing options...

KevinE Posted April 6, 2009 Share Posted April 6, 2009 The Solar 250 cassettes use synchronous motors which are locked to the mains frequency. So, as someone else has said, you need a different gearbox, you cant just change the motor current with a resistor. http://www.opti-kinetics.com/images/stories/250SEFFE.jpg Link to comment Share on other sites More sharing options...
