Title:
COMPRESSION MACHINE, HEAT PUMP DEVICE, AIR CONDITIONER AND REFRIGERATING MACHINE
Document Type and Number:
WIPO Patent Application WO/2014/097478
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a compression machine capable of balancing the entire force of the rotating portions without a balance weight while minimizing a decrease in the valid amount of magnetic flux, and reducing vibration and noise during rotary driving. The compression machine according to the present invention comprises: a motor having a rotor (10) including magnets (14a, 14b) opposite each other; a compression unit for compressing a refrigerant; and a crank shaft connected to the motor and the compression unit and configured to transmit the rotary drive from the motor to the compression unit. The magnets (14a, 14b) are arranged so that the difference of magnetic force between the opposing magnets (14a, 14b) cancels a force which makes the crank shaft bend during the rotary driving.
