Patent number: 6198184Abstract: In order to protect a brushless motor, heat generated at a switching device, in response to an abnormality, activates a protection device. The protection device includes a connecting line communicating between a source supply line and the switching device. The protection device is provided near the switching device such that it can sense heat at the switching device with a high degree of sensitivity. Thus, when excessive heat is generated at the switching device, the protection device reaches a specific temperature, whereby the source supply line becomes cut off from the switching device, thereby immediately stopping the operation of the brushless motor.Type: GrantFiled: January 7, 1998Date of Patent: March 6, 2001Assignee: Zexel CorporationInventors: Shinichi Ohi, Hiroshi Ohsawa, Kazuyoshi Horiuchi, Kouji Ando

Patent number: 5936364Abstract: A pulse width of a drive pulse of a brushless motor is modulated in correspondence to a setting signal for setting the rotation rate. Switching control for the current supplied to exciting coils is implemented by using an output signal from Hall elements for detecting the position of the rotor and the drive pulse. Correction of the pulse width of the drive pulse is implemented to ensure that the average voltage is maintained at a constant level even when the source voltage fluctuates so that stable rotation can be maintained over the entire rotation rate range even when the source voltage supplied to the brushless motor fluctuates and so that the fuse can be prevented from melting and the motor can be prevented from becoming damaged, which may otherwise be caused by a fluctuating source voltage.Type: GrantFiled: February 5, 1998Date of Patent: August 10, 1999Assignee: Zexel CorporationInventors: Hiroshi Ohsawa, Shinichi Ohi, Kzuyoshi Horiuchi, Kouji Ando

Patent number: 5907226Abstract: An object of preventing a reduction in the output efficiency of a motor in the high speed rotation range and reducing the noise of the motor in the low speed rotation range is to be achieved. Since, if a signal that corresponds to the rotation rate has a value equal to or smaller than a specific value, the timing with which a switch performs switching is retarded relative to the timing used when the signal corresponding to the rotation rate has a value larger than the specific value, once the operation shifts to the low speed rotation range, the switching timing is retarded to shift from the setting that gives priority to efficiency, to the setting for achieving noise reduction as long as the switching timing is set in advance so that an optimal output efficiency is achieved in the high speed rotation range.Type: GrantFiled: February 3, 1998Date of Patent: May 25, 1999Assignee: Zexel CorporationInventors: Hiroshi Ohsawa, Shinichi Ohi, Kzuyoshi Horiuchi, Kouji Ando

Patent number: 5901268Abstract: In order to prevent the performance of a motor from deteriorating due to a change in which the rotation rate of its rotor is to be increased suddenly, in a brushless motor in which a drive pulse whose pulse width is modulated in correspondence to a rotation rate setting signal input from the outside is formed and switching control is performed on the current supplied to the exciting coils by using output signals from the Hall elements that detect the position of the rotor and the drive pulse, the pulse width of the drive pulse is changed gradually and greatly until it reaches the pulse width that corresponds to the rotation rate setting signal when the upward change in the rotation rate of the rotor is to be large.Type: GrantFiled: February 5, 1998Date of Patent: May 4, 1999Assignee: Zexel CorporationInventors: Kouji Ando, Kzuyoshi Horiuchi, Shinichi Ohi, Hiroshi Ohsawa
