PROBLEM TO BE SOLVED: To provide motor driving equipment which can prevent fusion of a relay contact, by maintaining a closed state until a temperature of the relay contact sufficiently decreases, and preventing a large current from flowing through the relay contact in the state at a high temperature. SOLUTION: This motor driving equipment is provided with a control means 2 having a switching means 7, an target current signal setting means 8, a driving control means 9 and a relay holding means 10. A relay holding signal RH (H level) is supplied to a relay circuit 3 for a specified time, e.g. one hour, which is set by a timer on the basis of a motor stop signal J OF (L level). As a result, a relay contact 3B is put in a holding state for a specified time. |
