Abstract: A motor and an electrical equipment having same. A conventional integrated bearing bracket (40) is divided into a stator bracket part (42) and a bearing support part (41), and a bracket insulating layer (43) is provided therebetween, equivalent to adding an insulating layer capacitance between the stator bracket part (42) and the bearing support part (41). Due to the configuration of the bracket insulating layer (43), an equivalent capacitance on the side of a stator (10) can be significantly reduced. In a loop of a high-frequency circuit, a shaft voltage is a divided voltage on either end of a bearing capacitor, and the equivalent capacitance on the side of the stator (10) is equivalent to be connected in series on the side of a bearing outer ring (32) of the bearing capacitor. Therefore, the configuration of the bracket insulating layer (43) reduces the equivalent capacitance on the side of the stator (10), such that either end of the bearing capacitor obtains a smaller divided voltage, i.e., the shaft voltage is reduced. The configuration of an electrode structure (60) can reduce the shaft voltage and a shaft current. The risk of occurrence of galvanic corrosion in a bearing (30) is reduced. For a motor having high power and using a large metal housing to improve mounting strength and ensure heat dissipation, the risk of damage caused by galvanic corrosion of the bearing (30) of the motor can be reduced.
