Abstract: A control circuit and method for DC motors is disclosed in the present application. The control circuit may comprise a voltage monitoring unit for monitoring the output voltage of the DC power supply, a switching circuit for controlling the operation of the DC motor, and a PWM signal output unit to output PWM signal for controlling the switching circuit. The PWM signal output unit may be configured to regulate the duty cycle of the output PWM signal based on the results of the voltage monitoring unit. In this way, motors with different resistances may work continuously in a stabilized state. Also, it may detect when a load like motor is heavy loaded or overloaded, stop motor from starting, and avoid overtime working due to the drop of supply voltage damaging the load like motor. When the voltage of power supply is higher than the rated voltage of the motor, it may regulate the input voltage value of power supply to avoid the increase of excitation current of motor with the increase of the applied voltage, thereby avoid the loss of iron core.

Abstract: An apparatus and method for resetting a motor controller. It is determined whether a tripping of the motor controller is accompanied by an undesired condition elsewhere in a power system wherein an alternating current bus receives alternating current power from a generator, a power converter converts the alternating current power on the alternating current bus to direct current power on a direct current bus, and the direct current power on the direct current bus powers the motor controller. In response to a determination that the tripping of the motor controller is accompanied by the undesired condition, it is determined whether the undesired condition is less than a threshold for more than a time delay. The motor controller is reset in response to a determination that the undesired condition is less than the threshold for more than the time delay.

Abstract: An electric motor includes a rotor and a stator. Apart of the rotor includes a first frictional portion forming a movement locus. The stator includes a second frictional portion which brakes and stops the rotation of the rotor by a mechanical frictional force produced by contact between the second frictional portion and the first frictional portion, and a braking actuator which does not allow application of braking by shifting the second frictional portion away from the first frictional portion during power supply to the electric motor, and allows application of braking by pressing the second frictional portion against the first frictional portion during cutoff of power supply to the electric motor.

Abstract: A motor start circuit for an AC induction motor employs a DC relay whose NC contacts are placed in series with the start capacitor. A half full-wave rectifier arrangement has an AC input connected to the junction of the relay switch and the start capacitor, and DC outputs applied across the relay actuator coil. In the event of intermittent application of power to the motor, any residual charge on the start capacitor will feed current to the actuator coil to hold the relay switch open until the residual charge has decayed sufficiently, to avoid damage to the motor from capacitive discharge. A high magnetic retentivity core can be used to hold the relay off for sufficient time for stored energy to dissipate.

Abstract: A motor control system includes a drive motor and a deck motor that are connected to a battery, an ECU, and a key switch. The key switch acquires that an operation unit has been turned on, and transmits a restart permission signal to the ECU. When SOC of the battery reaches or falls below a first threshold set in advance, the ECU performs a step of disabling all the motors, and when the restart permission signal is received, the ECU performs a step of executing a decelerated travelling mode where the disabled state of the drive motor is released and an allowed speed of the drive motor is reduced.
