PROBLEM TO BE SOLVED: To provide a motor driver that can detect a motor lock on the basis of driving signals from a microcomputer.SOLUTION: The motor driver is configured to detect a motor lock by detecting inputs of driving signals. The motor driver includes a motor lock detection circuit 33 for outputting a motor lock protection signal if, after one of driving signals of three phases (Lin1, Lin2, Lin3) is input, all the driving signals of the three phases (Lin3, or Lin1 or Lin2) are not input before a preset motor lock determination time passes. |
