<P>PROBLEM TO BE SOLVED: To provide a motor driver capable of decreasing the number of component in a device for driving a plurality of motors such as air conditioner outdoor equipment, and having a small number of input terminals. <P>SOLUTION: A motor driver 10 has three-phase inverter circuits 16 and 17 for driving motors 31 and 32. The motor driver 10 includes: a serial parallel signal converting portion 23 for converting a motor speed command of a serial signal into a motor speed command of a parallel signal to output the motor speed command to each three-phase inverter circuit; and a parallel serial signal converting portion 26 for converting a state signal of the parallel signal into a state signal of the serial signal to output the state signal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
