PROBLEM TO BE SOLVED: To easily detect the output of an electric motor without adding a specific electronic instrument in a controller. SOLUTION: A current limit element 7 limiting the amount of current in the electric motor 1 is connected between the emitter of and the drive IC4 of the lower stage transistor group 5b of a transistor part 5, grounded through the drive IC4, and the amount of current in the current limiter element 7 is detected by the drive IC4. |
