Claims

[Scope of utility model registration request]

A relay having a coil, a first make contact, and a second make contact, which is energized when a make contact type command switch is turned on and demagnetized when a break contact type command switch is released, and an on-delay type make contact and an on-delay type make contact. a first timer having a break contact in the form of a shape and a coil energized by the closing of the first contact of the relay;
a second timer having an on-delay type first make contact, an on-delay type second make contact, and a coil excited by the closing of the make contact of the first timer; an on-delay type make contact; and an on-delay type make contact; a third timer having a break contact and a coil excited by the closing of the first make contact of the second timer, and having a set time longer than the set time of the second timer; and an on-delay type third timer. a fourth timer having a first make contact, an on-delay type second make contact, and a coil excited by the closing of the make contact of the third timer; a second make contact of the relay and the first make contact; or through the on-delay type break contact of the timer or the on-delay type second make contact of the second timer and the third
A current is supplied through the on-delay type break contact of the timer or through the fourth on-delay type second make contact to a coil that is excited and a power supply line that supplies power to the wheel shaft motor. 1. A wheel shaft motor starting circuit for a machine tool, comprising an electromagnetic switch having an interposed contact.
