Heavy duty design
The electrical and mechanical design of ABB motors offers high performance values in all mounting arrangements, protection class and applications.
Insulation scheme
ABB low voltage motors employ a unique polyamide based class F insulation scheme rated for 1550C with temperature rise limited to class B. The advanced insulation of our motors gives high electrical and mechanical stability.
Winding
Motors are wound using high quality round enamelled wires conforming to IS:13730. To ensure long life, the stators are impregnated with a solventless resin resulting in good thermal conductivity and high mechanical strength.
Ventilation
Ventilation circuit has been optimally designed based on aerodynamic and acoustic considerations.

The BBL range of energy efficient motors Type " MH" are from 1.1 Kw ( Frame 90S) to 18.5 Kw ( Frame 160L). Use of these motors can lead to substantial reduction in energy costs. The payback periods are in the order of 3 to 6 months depending upon the usage. Even replacing existing motors with EE motors in power intensive industries gives paybacks within 1 to 2 years.
