Abstract

A brushless dc motor assembly including a brushless dc motor, and a control board having at least one output connected to a stator winding of said brushless dc motor for providing current flow to said stator winding. Control electronics on the control board control current flow to said stator winding using a microprocessor and based on desired motor operating characteristics. The control electronics include a housekeeping power supply for providing a stable 5v DC signal from a rectified AC line voltage. The control electronics also include a MOSFET output amplifier having a power zener diode connected to the drain thereof, said power zener dissipating temporary back emf resulting from switching of said MOSFET from an on to an off state. A hall device mounted to a stator of said brushless dc motor is also provided. The hall device provides a signal representative of the rotational speed of a rotor of said motor to the control board. The control electronics on said control board control said current flow to said stator winding responsive to said signal from the hall device. The control board is preferably attached to a heatsink whereby the heatsink is attached to MOSFETS on said control board for dissipating heat generated by said MOSFETS.
