Appeal No. 96-2168
Application No. 08/257,478
rejection of claims 1 through 17, all of the claims pending in
the present application.
The invention relates to a control device for
controlling a plurality of motors in an air conditioner, e.g.
a blower motor and a compressor motor. A single microcomputer
controls the rotation of each motor by generating the driving
signals for each motor. The driving signals are dependent on
a respective position detection signal from each motor, and
drive respective inverter circuits for each motor.
Representative independent claim 1 is reproduced as
follows:
1. A motor control device comprising: a plurality
of motors for driving respective loads; a microcomputer for
controlling the plurality of motors; position detecting means
for detecting a respective position of a rotor of each of the
motors and outputting a respective position signal dependent
thereon; drive means for individually driving each of the
motors, each drive means including switch means for switching
a connection between a DC power supply and a respective motor;
drive signal generating means for generating respective drive
signals for individually driving the respective motors in
response to corresponding position signals for each motor
inputted from the position detecting means to the
microcomputer, whereby the respective drive signals are
effective to selectively drive the switch means of the
respective drive means so that rotors of respective motors are
rotated in response to corresponding position signals, the
connection between the DC power supply and the respective
motors is switched so that a DC voltage from the DC power
