摘要： An electromechanical actuator power drive unit for dynamic braking is provided, comprising an electric motor with a stator, a rotor that rotates with respect to the stator, and windings fixed to the stator. There is a control unit configured to supply a current to the windings. When the control unit is not supplying current to the windings, an electrical device allows current to flow through a parallel current path to the windings. The new current is generated by the interaction of a roller connected with a gear set to the rotor. The roller, and therefore the rotor, is urged in a rotational direction by the translational velocity of a load in contact with the roller. The new current generated by the rotating rotor flows in the opposite direction as the first current supplied by the power supply unit and creates a dynamic braking torque in the electric motor.

摘要： According to one embodiment, a control device detects a field current in a rotary electrical machine, estimates a rate of rotation of a rotor of the machine based on the detected current, obtains a field voltage in the machine based on a difference between the estimated rate of rotation and a target rate of rotation, and controls the switching of an inverter based on the field voltage such that the rate of rotation follows the target rate of rotation. A permanent magnet using the machine is an R—Co permanent magnet containing 25 to 40 at % iron. The control device performs field-weakening control by increasing and decreasing the field voltage based on a negative-field current in accordance with the rate of rotation by a material of the permanent magnet.

摘要： A driving control apparatus includes a controller that generates a first signal for controlling turn-on to a brushless motor, a PWM signal generator that generates a PWM signal for driving the brushless motor by continuous turn-on with a sine wave, and an inverter that supplies a driving voltage generated based on the first signal and the PWM signal for the brushless motor. The controller generates the first signal so that a turn-on section represented by the first signal continuously increases from a reference turn-on angle according to increase of a rotation speed, and the turn-on section having an angle corresponding to the continuous turn-on is kept when the rotation speed is equal to or greater than a predetermined speed. The PWM signal generator outputs the PWM signal in a range including a rotation speed at which the turn-on section begins to increase from the reference turn-on angle and more.

摘要： The Brushless Multiphase Self-Commutation Controller or BMSCC is an adjustable speed drive for reliable, contact-less and stable self-commutation control of electric apparatus, including electric motors and generators. BMSCC transforms multiphase electrical excitation from one frequency to variable frequency that is automatically synchronized to the movement of the electric apparatus without traditional estimation methods of commutation and frequency synthesis using derivatives of electronic, electro-mechanical, and field-oriented-control. Instead, BMSCC comprises an analog electromagnetic computer with synchronous modulation techniques to first establish magnetic energy and then dynamically share packets of magnetic energy between phase windings of a multiphase, position dependent flux, high frequency transformer by direct AC-to-AC conversion without an intermediate DC conversion stage.

摘要： A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To allow easy and convenient access to empty portable electrical energy storage device compartments within the vehicles, if the vehicle comes within the vicinity of a collection, charging and distribution machine or other authorized external device such as a key fob or other wireless device of a user, an empty portable electrical energy storage device compartment that is closed or locked, is unlocked, unlatched or opened automatically. Also, if the portable electrical energy storage device compartment is in another desired state to have the compartment unlocked, such as having a portable electrical energy storage device in the compartment that has a charge level below a particular threshold, the compartment will likewise be unlocked, unlatched or opened automatically.

摘要： A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To allow easy and convenient access to empty portable electrical energy storage device compartments within the vehicles, if the vehicle comes within the vicinity of a collection, charging and distribution machine or other authorized external device such as a key fob or other wireless device of a user, an empty portable electrical energy storage device compartment that is closed or locked, is unlocked, unlatched or opened automatically. Also, if the portable electrical energy storage device compartment is in another desired state to have the compartment unlocked, such as having a portable electrical energy storage device in the compartment that has a charge level below a particular threshold, the compartment will likewise be unlocked, unlatched or opened automatically.

摘要： An electromechanical actuator power drive unit for dynamic braking is provided, comprising an electric motor with a stator, a rotor that rotates with respect to the stator, and windings fixed to the stator. There is a control unit configured to supply a current to the windings. When the control unit is not supplying current to the windings, an electrical device allows current to flow through a parallel current path to the windings. The new current is generated by the interaction of a roller connected with a gear set to the rotor. The roller, and therefore the rotor, is urged in a rotational direction by the translational velocity of a load in contact with the roller. The new current generated by the rotating rotor flows in the opposite direction as the first current supplied by the power supply unit and creates a dynamic braking torque in the electric motor.
