Abstract
A motor compressor has a compression mechanism including compressor components such as a cylinder and a piston and a driving motor coupled to a power source for driving the compressor components through a crank mechanism, and a cut-off device for cutting off the driving motor from the power source. The cut-off device is adapted to cut off the driving motor from the power source when the rotational angle of a crank shaft of the crank mechanism is within a predetermined range at the time of shutting down of operation of the driving motor for minimizing the vibration of the motor compressor.
