Abstract: A drive motor control device for a video disk player or the like operates to brake the motor by driving it reversely upon reception of a rotation termination signal, until it is detected that the motor has stopped and rotates reversely. The motor is then driven forwardly for a predetermined time before being allowed to rotate freely to a stop.

Abstract: A control circuit for a DC capstan motor used for driving a tape having control signals thereon is adapted for accurate stopping of the tape during intermittent-motion operation. A frequency generator coupled to the motor generates a frequency signal whose frequency is proportional to the motor's speed. A position signal generating circuit generates a position value that increments by steps upon occurrences of the frequency signal. A clamp circuit clamps the position value to a clamping level upon detection of the control signals. A brake start signal generator provides a brake start pulse signal when the position value exceeds a predetermined threshold, and this brake start pulse signal is used to commence braking of the motor. In order to permit accurate stopping in both forward and reverse directions, the clamping circuit provides one clamping level when a forward mode is selected and another clamping level when a reverse mode is selected.

Abstract: A system for accurately stopping a motor operated positioning device permits satisfactory motor tolerance limits for economical production by incorporation of a processor controlled motor plugging routine. The plugging routine includes an initial reverse polarity pulse to the motor of a duration sufficient to brake an ideal motor operating in the device. To accommodate motor characteristics within tolerance limits, a plurality of alternating bursts of positive and reverse polarity are applied to the motor following the initial pulse. Each of the alternating bursts is for a duration less than the system response time.

Abstract: A velocity at the time when the accelerator of a vehicle is released is stored under a certain condition in advance, and the stored vehicle velocity and an actual vehicle velocity are compared. When the actual vehicle velocity becomes greater than the stored vehicle velocity by a predetermined value, the downward inclination of a running road surface is regarded as exceeding a predetermined value, and safety means such as a brake is driven. As compared with a case of employing an inclination angle sensor such as a mercury switch, the device operates accurately without being influenced by a change in the vibration or acceleration of the vehicle.

Abstract: In control circuits for controlling D.C. electric motors, the motor is supplied in pulses so that the mean power supplied to the motor is varied by varying the frequency and/or mark-space ratio of the generator pulses. In such arrangements electrical braking is obtained by reversing the field winding connections but the field current has to be kept relatively low even for heavy braking. In the present invention means are provided for ascertaining if the armature current exceeds the field current during each pulse of current and for restricting the range of current which can be applied to the motor if the armature current exceeds the field current by a predetermined amount.

Abstract: A motor, moving at a known speed, is stopped in a controlled manner by a speed control servomechanism which compares the actual speed-versus-distance deceleration profile to an optimum or desired speed-versus-distance deceleration profile, and variably controls the reverse energization, or plugging, of the motor in a manner devised to achieve the desired profile. When the speed servo has reduced motor speed to a low level, and preferably zero, a stop-lock control servomechanism is enabled to position and maintain the motor at a preselected stop-lock position. The stop-lock servo implements a motor-control algorithm which, for a given position error, provides a higher magnitude motor energization when the motor is moving away from the stop-lock position than when the motor is moving back toward the stop-lock position. This control algorithm provides increased servo gain when the motor is moving away from the stop-lock position.

Abstract: A dynamic braking system utilizing a switch that is operated by the accelerator of the truck, and that acts through a relay to move contacts that electrically reverse the traction motor of the truck when the accelerator moves to neutral position. The traction motor is driven by pulsating power that is applied also when the accelerator is in neutral position so as to brake the truck. Pulse limit means control the motor current while braking, and permit an increase in the pulse duty cycle when the truck substantially comes to rest and the braking effect ceases. The duty cycle, upon reaching a certain value, acts through the charging of a capacitor to operate transistors forming parts of a control circuit. That causes a silicon controlled rectifier to bypass the relay, causing the motor reversing contacts to return to a normal position. The accelerator while in neutral holds further contacts open so as to prevent a movement of the truck when the reversing contacts move to normal position.
