Abstract: A driving apparatus of a motor capable of operating a motor of a reciprocating compressor stably by using a simple power voltage control unit. The apparatus includes a power voltage control unit for maintaining a power voltage supplied from a power supply unit as a certain value when a motor is operated, outputting the certain power voltage or cutting off the power voltage after a certain time has passed; and a capacitor for applying the power voltage supplied from the power supply unit to the motor when the power voltage control unit cuts off the power voltage.

Abstract: A frame of a reciprocating compressor includes a main frame having a cylindrical insertion hole to receive a cylinder of a compression unit along a center axis thereof and a flange that supports an outer stator of a reciprocating motor at the outer circumference of the flange. A sub frame is engaged to the main frame by an engaging device and positioned to cover an outer circumferential surface of the cylinder to form an oil flow path in a space between the main frame and the cylinder.
