摘要： A method and system of controlling driving of a brushless DC electric motor (BLDC) of an electric water pump are provided. The method includes estimating an initial position of a rotor using a magnitude of a current detected in a three-phase coil wound on a stator and converting a current magnitude that reflects a rotational angle of the rotor with respect to the initial position into two direct currents based on the three-phase current. The converted direct currents are output and a rotational angle, a speed, a flux and a torque of the rotor are acquired based on values of the three-phase current, a voltage generated according to flow of the three-phase current, a predetermined coil resistance, and an inductance input. A speed of the motor is then adjusted based on the acquired rotational angle, speed, flux, and torque of the rotor.

摘要： The present invention is an improved flow-metered pumping system using an air-backed diaphragm pump with load compensation. A variable motor speed controller is used to compensate for flow rate reduction caused by pressure effects. When the output pressure on the pump increases to a point where the load on the pump motor exceeds a specified threshold, the motor speed controller increases the speed of the motor to compensate for pressure induced diaphragm distortion losses and to achieve a substantially constant flow rate across a range of pump output pressures.

摘要： Apparatus features a microcontroller configured to: receive signaling containing information about a measured change of a magnetic field created by a magnetic circuit driving a motor; and determine corresponding signaling containing information about the speed of rotation of the motor, based upon the signaling received. The microcontroller provides control signaling containing information to control the operation of the motor, including where the motor control is used to control the flow of fluids from a pump. A Hall Effect Sensor is used to sense the magnetic flux and provide the signaling in the form of a feedback signal for implementing motor control. The motor housing has a slot, the Hall Effect sensor is mounted external the motor housing over the slot, and a ferromagnetic bridge is arranged over the Hall Effect sensor to close the magnetic circuit and cause more flux to go through the Hall Effect sensor.
