The Integrated Motor Assist (IMA) Hybrid Electric Vehicle (HEV) technology used in Civic Hybrid or Insight is developed originally by Honda, and is mounted in a V6 Accord with the aim of enhancing fuel economy of a mid-size passenger car. The development goal was to realize a mid-size passenger car that provides acceleration performance superior to a V6 Accord and the fuel economy of a compact class vehicle. Various means are employed to achieve high torque and high efficiency simultaneously, including an Interior Permanent Magnet (IPM) type rotor, low-loss electrical steel sheets as the stator material, and high maximum energy product magnets. These technologies increase the maximum power of the newly developed motor by approximately 20%, the maximum torque by 26% and motor efficiency over all ranges by approximately 1% to 3% compared to the current Civic Hybrid motor. Consequently, the maximum motor power of 14 kW and maximum motor torque of 136 Nm are achieved.
