Title: Detection of damage to coil of motor
Inventor: UCHIUMI KENICHI
IPC: G01R31/06
Filed: 1990-05-28
Abstract: PURPOSE:To enable detection of exfoliation of an insulating film of a coil on the occasion of insertion by impressing a low voltage on the coil and a coil inserting machine and by detecting this low voltage. CONSTITUTION:A detecting device 12 is connected to a lead-out wire 15 of a coil 2 and a base 4 of a coil inserting machine 1 and a DC low voltage is impressed on the coil 2 and the base 4 from a converter 13. Besides, the detecting device 12 makes a minute current flow through the coil 2 by the converter 13 converting an AC power supply into the low voltage, so as to prevent the coil 2 from being heated by this current for detection and damaged by burning. By inserting the coil while making the low voltage act on this coil and the coil inserting machine inserting it, exfoliation of an insulating film of the coil in a process of insertion can be detected from the presence or absence of the minute current.

Abstract: PURPOSE:To permit sufficient cooling after defrosting as well as the quick cooling of stored matters, whose temperature is risen upon the defrosting, to an objective temperature by a method wherein the title freezing refrigerator is operated after the defrosting at the lower limit of a corrected set temperature set at a lower setting temperature in accordance with the increasing width of a temperature in the refrigerator upon defrosting. CONSTITUTION:In a front surface opening type open cold storage showcase 1, the chambers of an open space 7 are intercepted from atmosphere by inner and outer double air curtains 8, 9. After defrosting, a lower limit temperature is set at a lower temperature in accordance with the increasing width of a temperature in the showcase upon defrosting to effect cooling operation control based on the newly corrected set temperature and prevent the delay of cooling of stored matters due to thermocycle operation started before arriving at the objective values of a temperature in the showcase and the temperature of stored matters when the operation is controlled based on a lower limit value of temperature before changing the set temperature. The lower limit value of the corrected set temperature is changed so as to be returned to the initial set temperature gradually and the continuation of cooling operation is decided by comparing the lower limit value with the temperature of circulating air and when the temperature of the circulating air has become higher than the initial lower limit value or the same temperature does not become higher than the lower limit value for a given period of time, the operation is controlled by a normal lower limit value after that time.
