Abstract: A control system for a sump pump driven by an AC motor includes an AC power line having an input adapted for connection to an AC power source and an output adapted for connection to the AC drive motor. A controller is connected to a controllable switch in the AC power line, to control the opening and closing of that switch. Redundant float switches are coupled to the controller and adapted to be mounted in a sump to supply the controller with a signals when the liquid in the sump rises to a selected level. A timer in, or coupled to, the controller alters the control signal to open the controllable switch if the liquid level in the sump remains above the selected level for a preselected time period.

Abstract: A brake system and method for a direct current brushed motor without a Hall sensor are provided. After the system is activated, the motor is pre-braked in order to detect and record the stationary armature current while the motor is in a stationary state. As the motor is required to be braked, a reverse control voltage is generated and then the armature current value is detected. When the detected armature current value is equal to the stationary armature current value, the operation of braking the DC brush motor is accomplished. The invention can achieve the goal of braking the motor to a stop quickly, no matter which state the motor is in. Besides, it can be applied to different kinds of motors.

Abstract: The present invention provides efficient dynamic braking of a DC motor to complement servo loop control. This invention uses a combined technique where, first, a reversed-torque signal is applied to a standard motor controller that then reverses armature current to initiate braking and, second, a dissipative load is switched between the DC voltage bus and ground in order to dissipate the regenerated current as the motor slows. As braking action continues, the dissipative load is repeatedly switched into and out of the circuit, whenever voltage on the DC voltage bus, caused by regenerated current, exceeds a selected threshold. Hysteresis is provided to maintain current flow for a controlled period, providing a pulse-width modulation of the switching action. The invention allows controlled, fast braking for repeated operations and improves overall servo positional control in high-inertia applications, such as for an image processing apparatus using an imaging drum. This invention also permits controlled braking in the event of power loss, using regenerated energy from the motor to power braking control circuitry.

Abstract: A DC motor is supplied, from a motor driver, with a brake voltage constituted by a forward drive voltage, a reverse drive voltage, and a stop voltage of a zero potential level. An operational current of the motor driver is supplied to a low-pass filter whose output is supplied to first and second sample and hold (S/H) circuits. The first S/H circuit performs its sampling operation after a minute period of time in which the brake voltage goes through a polarity inversion from the reverse drive voltage to the forward drive voltage. The second S/H circuit performs its sampling operation after a minute period of time in which the voltage applied is changed from the forward drive voltage to the reverse drive voltage. The outputs or sampled values of both S/H circuits are compared with each other by a comparator. When the sampled values equal each other, i.e., when the number of rotations of the motor becomes zero, the comparator outputs a coincidence pulse. This pulse is supplied to a stop detector. When detecting this coincidence pulse a predetermined number of times in a row, the stop detector determines that the number of rotations of the motor has become zero.

Abstract: A silent, high torque, impulse actuator system for low average power devices. The system incorporates a typical small three pole D.C. motor which has been modified to allow quick electrical conversion, with unipolar switching circuitry, from conventional rotation, to silent magnetic braking at a stop position; and then to a normally OFF condition.The high efficiency of this intermittent drive system is enhanced by the unique combination of being normally off between actuations; the high efficiency of the D.C. motor during start conditions; and the use of a round cam to provide a cosine power stroke that utilizes the inertia of the motor rotor to maximum mechanical advantage.
