The most important advantages of a drive:
- high rotation speed
- silent work
- improved durability and reliability of operation
- soft start
- simpler drive installment
The use of cogwheel gear enabled to high rotation speed. In addition – by applying the variable frequency drive- control of rotary motor has been improved. On the one hand soft start system enables high telescope position tracking accuracy. On the other hand – thanks to faster full rotary speed - the dome executes long movements shorter. Full revolution of a dome lasts less then 2 minutes. Soft start induces also minimal gear wearing-out. In addition a cog-rim lets to get rid of encoder tape, durability of which was frequently questioned by our clients. Now the encoder works with aluminum cogs of driving rim directly.
