    摘要： A bulk materials pump feeder having a housing and a rotating drive rotor for transferring material from an inlet to an outlet of the housing. The drive rotor has a hub. Drive disks extend away from the hub toward a housing inner wall. Three structural features of the feeder reduce the tendency of material to jam between the drive rotor and the housing or other stationary parts. First, the distance between the circumferential edges of the drive disks and the housing inner wall increases from the inlet to the outlet in the direction of rotation of the drive rotor. Second, a low-friction brush seal disposed on the periphery of the drive disks seals the area between the periphery of the drive disks and the inner wall. Finally, a materials scraper having a flexible tip is mounted in the housing and extends into the drive rotor between the drive disks.

    摘要： A bulk materials pump feeder having a housing and a rotatable drive rotor mounted in the housing for transferring material introduced into the housing through an inlet to an outlet for discharge of the material from the housing. The drive rotor has a hub and a plurality of drive discs extending away from the hub toward an inner wall of the housing. To reduce the tendency of material passing through the housing to wedge between the inner wall of the housing and the circumferential edges of the drive discs, the distance between the circumferential edges of the drive discs and the inner wall of the housing increases from the inlet of the housing to the outlet of the housing in the direction of rotation of the drive rotor.

    摘要： A hybrid DC motor controller is provided for driving a DC motor. A switch is connected in series with the DC motor, and a capacitor is coupled in parallel with the DC motor and the switch. The speed of the DC motor is controlled by the capacitor voltage and the duty cycle of a pulse-width modulated (PWM) signal supplied to the switch. The hybrid controller combines a motor speed control loop with a PWM optimization loop. The motor speed control loop generates a PWM signal in response to the speed of the DC motor and conducts that PWM signal to the switch to control the DC motor. The PWM optimization loop includes a controller that is responsive to the PWM signal and an AC voltage signal. This controller compares the PWM signal with a PWM signal setpoint, and drives the PWM signal toward the PWM signal setpoint by adjusting the capacitor voltage in response to the comparison between the PWM signal and the PWM signal setpoint. The speed of the DC motor changes in response to the adjusted capacitor voltage, and the motor speed control loop changes the PWM signal in response to the changed motor speed. These adjustments have the cumulative effect of driving the PWM signal toward the PWM signal setpoint. The controller included in the PWM optimization loop controls a rectifier for selectively supplying a rectified voltage to the capacitor.
