Accordingly, the braking force by the brake module 112a-1 is transmitted to the power shaft 112c to limit the rotation of the power shaft 112c, thereby limiting the rotation of the motor 101 to generate a load. The brake module 112a-1 is preferably applied with a powder brake in order to alleviate the impact caused by a load, and may be cooled by a separate cooling means (not shown).

Accordingly, the clutch control switch 113e can easily generate an abnormal state in which the transmission of the driving force of the motor 101 is blocked, and thus the response of the motor 101 can be checked.

The electric operation unit 13 is configured to artificially generate an electrical abnormal state for the motor 101, and as shown in FIG. 5, a short circuit operation unit 131 for generating a short circuit of the stator coil 101a-1; It may include a leakage control unit 132 for generating and measuring the leakage current, and an electric control panel 133 for controlling the operation of the electrical control unit 13 .

The short-circuit switch 131b can be operated to be controlled by a short-circuit switch operation module 133a, which will be described later, of the electric operation panel 133, so that a short circuit can be easily generated from the outside through the short-circuit switch 131b. can make it go away

The leakage control unit 132 is configured to generate a leakage current from the motor 101 and measure the leakage current, so that the accuracy of the leakage current measurement can be tested. In particular, the leakage control unit 132 may measure the leakage current value while changing it in various ways to test the accuracy of leakage current measurement over a wide current range. To this end, the leakage control unit 132 includes a ground wire 132a having one end connected to the stator coil 101a-1 of the motor 101 and the other end grounded, and a plurality of ground wires connected in parallel on the ground wire 132a.

The ground line 132a is connected to the stator coil 101a-1 and draws a current flowing through the stator coil 101a-1 to the outside, so that a certain amount of current leaks through the ground line. However, since the amount of current flowing through the ground line 132a is very large and its size cannot be precisely specified, a plurality of variable resistors 132b are formed in parallel between the ground lines 132a to form a resistance value of each variable resistor 132b. Accordingly, a current value passing through the variable resistor 132b can be made constant, and it can be checked whether an accurate current value is measured by measuring it.

The variable resistor 132b is formed in plurality and connected in parallel on the ground line 132a, so that the amount of current passing through the variable resistor 132b is limited according to the resistance value. The plurality of variable resistors 132b are formed to have different resistance values, respectively, so that the current value changes depending on which variable resistor 132b flows through. In addition, an earth leakage switch 132c is formed on one side of each variable resistor 132b connected in parallel to control the flow of current through each variable resistor 132b.

The earth leakage switch 132c is formed in each variable resistor 132b to control the flow of current passing through each variable resistor 132b, and when the earth leakage switch 132c is closed, through the variable resistor 132b. Current flows, and when the earth leakage switch 132c is opened, no current flows through the corresponding variable resistor 132b.

In addition, the operation of the earth leakage switch 132c is controlled by an earth leakage switch operation module 133b to be described later of the electric operation panel 133, and individual operation of the plurality of earth leakage switches 132c can be controlled. Thus, only one earth leakage switch 132c can be operated or a plurality of switches can be operated at the same time, and the total resistance value is changed according to the resistance value of each variable resistor 132b and the number of the variable resistors 132b to be operated. The value of the current passing through the resistors 132b may be variously changed.

The current measuring terminal 132d is formed between the variable resistor 132b and the ground line 132a to measure the current value of the current passing through the variable resistor 132b, and the electric operation panel 133 is provided. The configuration of the motor starting board 100 for measuring the leakage current of the motor 101 by being exposed to the outside through the connection may be connected to measure the current value. Therefore, the leakage control unit 132 controls the operation of the earth leakage switch 132c to generate leakage currents of various current values and to measure the current values of the leakage currents through the current measurement terminal 132d, so that various leakage currents It can be checked whether the leakage current can be accurately measured for the current value range of .

The short-circuit switch operation module 133a is configured to control the operation of the short-circuit operation unit 131, and is formed to close or open the short-circuit switch 131b. Accordingly, the short-circuit switch operation module 133a can cause an artificial short circuit by opening the commercial short-circuit switch 131b.

The earth leakage switch operation module 133b is configured to control the operation of the leakage operation unit 132, and is formed to close or open each of the earth leakage switch 132c. Therefore, the earth leakage switch operation module 133b can select the variable resistor 132b through which the current passes, and the amount of current flowing to the current measuring terminal 132d is determined according to the selected variable resistor 132b. . In other words, when the earth leakage switch 132c is closed according to the operation of the earth leakage switch operation module 133b, a current flows to the variable resistor 132b formed on the closed earth leakage switch 132c side, and each variable resistor 132b. are connected in parallel to the current measuring terminal 132d, so that different currents flow to the current measuring terminal 132d according to the combination of the variable resistor 132b.
