Title: Controller and control method for brushless motor employing sensorless detection of commutating position
Inventor: HOLLING GEORGE H
IPC: H02P6/00
Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To detect the commutating position accurately and continuously by comparing the current variation rate waveform of each stator coil with a predetermined threshold voltage thereby determining an active stator coil. SOLUTION: A motor 2 has four stator coils 4, 8, 12, 16 and a plurality of current sensors 42, 44, 46, 48 detect currents flowing through the stator coils 4, 8, 12, 16 and supply the current waveform thereof to a switch circuit 34. On the other hand, differentiation circuits 62-68 determine the current variation rate waveforms and comparators 72-78 compare respective current variation rate waveforms with a threshold voltage predetermined by a variable voltage reference level 36. Subsequently, a sample-and-hold module 38 detects an active stator coil. According to the method, a commutation point can be detected accurately.

Grooves 12 are formed on both ends of a base plate of the front surface plate 1 by a diamond blade. Grooves are formed on both ends of a base plate of the back surface plate 2. A PDP whose original performance is lost is recovered from market, immersed in etchant for selectively dissolving glass containing lead, and separated into the front surface plate 1 and the back surface plate 2. Deteriorated MgO and a fluorescent part are removed, and new MgO and fluorescent part are formed so as to be recycled as a new panel. Since the grooves 12 are preformed on the front surface plate 1 and the back surface plate 2, etchant is prevented from permeating the inside.

Filed: 1994-11-21
Abstract: PURPOSE: To surely measure the moving speed, moving amount of a moving body in a wide range from a high to low speed by switching and detecting a touch roll-type measuring means and a laser Doppler speed-measuring means. CONSTITUTION: When a switching means 40 is connected to a touch roll-type speed-measuring means 20, the means 20 detects the rotation number per unit time and rotation direction of a touch roll 21 in touch with a moving steel plate 11 and transmits to an operating means 50 via the means 40. The means 50 counts/operates thereby to measure the moving speed, moving amount of the steel plate 11. On the other hand, if the means 40 is connected to a laser Doppler speed-measuring means 30, the means 30 outputs a laser Doppler frequency proportional to the moving speed of the steel plate 11 as a pulse signal, and the means 50 counts/operates to measure the moving speed, moving amount of the steel plate 11.  At this time, when a judging means 60 judges that speed data from the means 20 (30) are larger (smaller) than a predetermined speed, the means 20, 30 are switched to operate via the means 40.

Filed: 1992-10-26
Abstract: PURPOSE:To prevent condensation on a casing and a fan respectively by a method wherein the flow rate of ventilating air and the opening degree of the flap of a fan as well as the operating frequency of a compressor are detected respectively based on the detecting signals of an outdoor air temperature and a room temperature while the heating degree of refrigerant is controlled in accordance with the detecting results. CONSTITUTION:The microcomputer 4 of an indoor air-conditioning machine 10 detects the flow rate of ventilating air of a fan 8, the opening degrees of opening and closing flaps 12 of the fan 8 and the operating frequency of a compressor 2 respectively based on respective detecting signals of an outdoor temperature sensor 15 and a room temperature sensor 16. In this case, the detecting operations are effected when the outdoor temperature and a room temperature are lower than respective predetermined values and a difference between the room temperature and a set temperature is lower than a predetermined value. When the operating frequency is minimum and the flow rate of ventilating air is small, these values are changed to middle values. When the opening degree of the flap 12 is small, the opening degree is changed to a middle value. According to this method, the heating degree of refrigerant in a heat exchanger is increased to prevent condensation on a casing 11. On the other hand, the super heating of the refrigerant is reduced under another specified condition to prevent the condensation on a fan 8.
