Title:
MOTOR CONTROL DEVICE AND COMPRESSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/155270
Kind Code:
A1
Abstract:
When a compressor (33) is determined to be in operation, the operating RPMs (the actual work RPMs) are saved to a buffer. A determination is made as to whether a fault is an IPM fault. A determination is then made as to whether an IPM fault in a low-RPM region has been found. If an IPM fault in a low-RPM region has been determined to be found, the RPMs that are saved in an error buffer are set to the minimum RPMs.
