<p>The present invention provides for a transport refrigeration unit (100) of the type configured to be mounted on the front wall of a transport trailer, comprising a compressor (116), a condenser heat exchanger (114), an evaporator heat exchanger (112), at least one fan assembly (141 a, 113a) having at least one electric fan motor (141b, 113b) configured to provide air flow over one of the heat exchangers (114, 112), and an integrally mounted unitary engine driven generator assembly (400) configured to selectively produce at least one A.C. voltage at one or more frequencies. The generator assembly is capable of producing sufficient power to operate the compressor drive motor (118) and the at least one fan motor (141b, 113b). In a preferred embodiment, the generator assembly (400) is a synchronous generator and the compressor drive motor (118) and the at least one fan motor (141b, 113b) are configured to be directly coupled to the generator (300) and to operate at a voltage and frequency produced by the synchronous generator (300).</p> |
