Railways are being electrified because of simplicity in the construction, operation and maintenance of electric locomotives. Electric locomotives are also economical compared to diesel/gas locomotives in terms of running cost and maintenance cost. They reduce air and noise pollution. A traction motor is the most common form of an electric motor used for the propulsion of railway engines.
Many other types of motors are being used in electric locomotive apart from traction motor. These different types of motors are collectively known as the Auxiliary Motors.
All the motors are of AC, 3-phase and squirrel cage induction type that are robust and require negligible maintenance. LHP has been supplying auxiliary motors to railways for over 20 years and is recognised as a quality manufacturer of electric motors. Typical applications where our motors are being used, include

• Transformer oil circulating pump
• Rectifier cooling blowers
• Air compressors
• Vacuum pumps
• Dynamic braking resistance cooling blower
• Main starting resistance cooling blowers
