WHY MOTOR DRIVE UNIT?
- Mechanism
MOTOR DRIVE UNIT
The drive mechanism is built with a specialised series of gears to ensure smooth operation. The uniform mounting and drive geometry significantly enhances fitment.
The housing made of corrosion-resistant cast aluminium makes it perfect for any environment, even the most extreme operating conditions. The mechanism is tested for IP-56 Protection, and a special housing is available for IP-66 as well. The motor drive is built with all necessary safety features.
EMR is also equipped to provide additional electrical features, if required, in the motor drive unit. On-site solutions with integrated electronics for direct regulation and monitoring of on-load tap changers and transformers can be built and integrated into the motor drive.
