the coupling part 220 support part 230 and second mounting member 250 i e a plurality of the legs should further include the bead 260 in order to facilitate the coupling to the washing machine 100 the mount 200 is preferably provided to the topside of the case 110 moreover in order to prevent the heat generated from the dynamic braking resistor 150 from being transferred to the case 110 and the device of the washing machine 100 the mount 200 is formed of a material having a low heat transfer coefficient specifically at least one of the coupling part 220 support part 230 and second mounting member 250 i e a plurality of the legs is formed of a material having a low heat transfer coefficient an operation of the washing machine 100 using the bldc motor 130 according to the present invention is explained as follows first of all the mount 200 having the dynamic braking resistor 150 coupled thereto is fixed to the topside of the case 110 when the dynamic braking resistor 150 emits heat the mount 200 prevents the heat from being transferred to the topside of the case 110 and the device of the washing machine 100 hence the topside of the case 100 and the device of the washing machine enable to avoid being transformed by the heat namely while the dynamic braking resistor 150 is coupled to the first mounting member 210 the second mounting member 250 extending from the first mounting member 210 is coupled to the topside of the case 110 or the device of the washing machine in this case as the second mounting member 250 has the length greater than the height of the dynamic braking resistor 150 the dynamic braking resistor 150 is separated from.
