BRUSHLESS MOTOR FOR DRAINAGE PUMP AND DRAINAGE PUMP

摘要

A brushless motor for a drainage pump and a drainage pump. The brushless motor for the drainage pump comprises: a motor shell (11); a motor shaft (221); a rotor assembly (222), mounted on the motor shaft (221) and synchronously rotating with the motor shaft (221), and comprising a rotor core (2221) and a rotor pole (2222) embedded on the rotor core (2221); a stator assembly (223), comprising a stator core and a three-phase stator winding twined in a stator core groove; and a control panel (224), comprising a three-phase inverter circuit and a circuit control component, the circuit control component controlling, by using a space vector pulse width modulation technology, a three-phase voltage that is output by the three-phase inverter circuit to the three-phase stator winding on the stator assembly, and the control panel (224) being received in the motor shell (11). The brushless motor for a drainage pump and the drainage pump are used in a dishwasher or a washing machine.
