Embodiment Construction
[0034] Embodiments of the invention are described for a lead frame for coupling an inverter for an electric motor or generator, preferably for the wheels of a vehicle, to a DC power supply. However, if the electric motor is located within the vehicle, it may be located anywhere within the vehicle. The motor is of the type having a set of coils which is part of a stator attached to the vehicle, radially surrounded by a rotor carrying a set of magnets attached to the wheel. For the avoidance of doubt, aspects of the invention are equally applicable to generators having the same arrangement. As such, the definition of electric motor is intended to include generators. Additionally, certain aspects of the invention are applicable to devices having a rotor centrally mounted within radially surrounding coils. As will be understood by those skilled in the art, the present invention is suitable for use with other types of electric motors.
[0035] For the purposes of this example, i...

Description
technical field [0001] The present invention relates to a lead frame, in particular a lead frame for forming a plurality of sub-motors. Background technique [0002] As interest in environmentally friendly vehicles increases, so does the interest in using electric motors to provide drive torque for vehicles. [0003] An electric motor system generally comprises an electric motor with a control unit arranged to control the power of the electric motor. Examples of known types of electric motors include induction motors, synchronous brushless permanent magnet motors, switched reluctance motors, and linear motors. Due to the high torque requirements required to propel the vehicle, the most common type of electric motor used for this purpose is a three-phase electric motor. [0004] Three-phase electric motors typically include three coil sets, where each coil set is arranged to generate a magnetic field associated with one of the three phases of an alternating voltage.
