WHY MOTOR DRIVE UNIT?

Uncompromising quality and reliability
The main objective of an Electric Motor Drive Unit is to drive the connected On-load tap-changer to a higher or lower tap of a transformer. Easun MR’s Motor Drive Units are known for their uncompromising quality and reliability standards. We offer four Motor Drive Units- MA-7, MA-9, MA-2 and AMD, and all of them meet the requirements of IEC 60214.
  • Mechanism

MOTOR DRIVE UNIT

Protect Transformer & OLTC from damage

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.
