The DC motor is not capable of any constant speed unless it has position feedback with expensive electronics. We provide a declination option to drive such a motor. These systems have the ability to drive Synchronous or Stepper motor for the RA drive. Power is required at 12V DC up to 0.6 amp. In common with our other drive boxes the RA motor is always driven and the handset only provides the adjustments.
All motors plug into the drive box so the electronics can be removed between sessions.
If you have an existing mains operated motor then a 50Hz supply is required which we supply as standard. If you are buying a synchronous motor then we need to know the slow motion reduction ratio. A specific gearbox will have to be calculated allowing the motor to work in the 42Hz to 80Hz range to give the correct reduction. Slow motion reduction ratio is required so that we can work out correct gearbox and drive frequency. The drive box can be fitted with options 7 or 9 and 10.
