A subsidiary of Tata Motors, Miljo Innovasjon has chosen TM4, a subsidiary of Hydro-Quebec, to supply electric motors, vehicle regulators, power electronics for an exhibition program of electric cars to be initiated in Norway in 2009-2010. Li-ion batteries are to be supplied by Electrovaya.
This exhibition program will make Miljo create more than one hundred units of an all-electric version of Tata Motors’ Indica Vista.
Tata Motors and Miljo will gain advantage from TM4’s latest production of motors for the industry of automobile, the TM4 MOTIVE series. An inverted rotor topology was utilized by the TM4 motors for utmost torque density.
The inverted rotor topology (wherein the rotor spins outside of the stator) has a bigger magnetic field, in contrast with rotor centric permanent magnet motors. The additional radius is a feature that increases torque and power density and provides improved competence.
Miljo will also utilize the MO 120. Its design permits larger output of power density over an extensive range of operating velocity. Aside from that Miljo will make use of a 60 kW peak regulator. The peak power of the unit will be 60 kW.
TM4 is also working to plan, expand, and exhibit a latest automotive electric powertrain with Magna, which is based on the high density permanent magnet motor of TM4.
Tata Motors Limited, India’s biggest and recognized automaker, has a revenue of US$ 9 billion last 2008. Miljo Innovasjon, meanwhile, creates electric versions of vehicles constructed and sold by Tata Motors.
