Claim Text:
1. A motor device, comprising: a motor unit comprising: a converter unit comprising: wherein the case of converter unit is connected to the motor unit at the installation surface of the motor unit; the first motor unit input terminal and the first converter unit output terminal are connected; the second motor unit input terminal and the second converter unit output terminal are connected; the third motor unit input terminal and the third converter unit output terminal are connected; the first motor unit output terminal and the first converter unit input terminal are connected; the first grounding terminal and the second grounding terminal are connected; the inverter drive circuit is structured to receive the analog control signal outputted from the microcomputer and output a drive pulse signal to be supplied to the inverter circuit; and wherein the microcomputer is configured to detect a terminal voltage across the second shunt resistor, to calculate a current value by using the terminal voltage and a resistance value of the second shunt resistor, to compare the current value with a specified current value, and to limit or cut off the output of the analog control signal when the current value exceeds the specified current value.
