200W motor power is regarded as continuous, so you do not need to be bothered anymore with observing your motors duty cycle time. However, under full load the heat of the motor casing will be such that it is not possible to physically handle for any length of time. It seems that, apart from excellent functional aspects, there was also a great consideration given to aesthetically please users, as the replacement motor with speed controller looks stunning. The vintage, retro style of the controller merges very well with the visual style of Unimat SL or Unimat 3.The free speed range for this motor is approx from 800rpm to 2700rpm. To add some personal feedback about this motor, I need to notice that once I replaced the old, original, 95W weak! , badly duty cycled Unimat motor, my first, surprisingly positive, impression was that my Unimats become "completely different (in a good sense) machines". I also experimented a lot with changing belts length with connection to variable speed, but my final, personal preference is to use just one belt and change the speed from minimum to maximum by simply turning the knob. This of course depends on what I do.
Because you can switch the motor on and off by pushing the knob down, this does not affect the pre-adjusted speed. You can switch it on and off and independently adjust the speed. This upgraded version comes with rotation direction switch, allowing users to quickly change the motor direction from clockwise to underclockwise and vice versa. I however would recommend you to spend some time and make few experiments with different belts lengths on different belt pulleys, so you can explore a large number of options for speed and torque.
You will need 3mm Allen key to do and undo grub screws in motor pulley, as the motor comes with 12mm, duoble pulley. It is the smallest size pulley available for this motor.
Other pulley sizes can be supplied on request. Also, you will need to adjust circumferential length of your polyurethane, 5mm drive belts.
Please contact me, if you need any help with your belts. Motor comes with standard UK mains, fused plug.Length of the robust, rubber power supply cable is 2m. Rejon was a company manufacturing high quality, expensive, different Unimat SL and Unimat 3 variable speed, replacement motors. However, Rejon seized to trade many years ago. Rejon type motors are cheap, badly and unprofessionally wired and thence dangerous, motors. They can be recognised by cheap, plastic, speed control boxes as contrary to quality die cast ones.
