Brushless DC Motor Control With Integrated Water in Filter Circuitry

摘要

A filter assembly combines the physical support, protection and electrical connections for a water in filter (WIF) circuit with the support, enclosure and electrical connections used for a motor control circuit that drives a BLDC motor in the filter assembly. Sharing space and electrical connections between what have been physically separate electronic circuits reduces the cost, materials and parts necessary to manufacture the filter assembly. In an assembly with a brushless motor-driven pump, the electrical connections from the host equipment to the motor can be shared with the WIF circuit, eliminating separate conductors and connectors.
