Abstract
A rotor, a motor, a compressor and a refrigeration apparatus are provided. The rotor has a rotor core, permanent magnets and multiple slits. The rotor core has multiple installation recesses. The permanent magnets are provided in the installation recesses to form magnetic poles. The multiple slits are arranged at the rotor core and positioned at respective sides of the installation recesses away from a rotation axis of the rotor. A connection line between central points of two end portions of the slit close to and away from the installation recess forms a direction line of the slit within a cross-section perpendicular to the rotation axis of the rotor. A central line of any magnetic pole passing through a central axis of the rotor core is defined as an axis d.
