摘要： An electric vehicle propulsion system includes an electric motor and a battery pack formed as a single, integrated unit. It is a self-contained, integrated electric propulsion system. It disrupts the long-established engineering paradigm that the electric motor and the battery pack have to be designed, built and installed as separate systems.

摘要： A helical-type explosively pumped flux compression generator (HEPFCP) capable of natively generating its own electrical current to successfully power the explosive phase of current generation required to power a load. It uses the chemical energy stored in a solid propellant to rotate an explosively laden dynamo armature inside a stationary solenoid winding. Thrust produced by burning propellant is directed by aerodynamic structures so it causes centripetal acceleration of the core thereby inducing an electromotive force in the solenoid winding, causing it to act much as a stator in dynamo. A rectifier rectifies this induced AC voltage into a DC current, then charges a capacitor bank. The propellant burns down to the explosive core, then the core expands, contacting the solenoid winding, forming a new circuit. The compression caused by the continuously expanding core will diminish the number of turns not short circuited, compressing the magnetic field, and creating an inductive current. At the point of greatest flux compression, a load switch is opened, and the maximum current is delivered to the load.

摘要： A power tool is provided including: a housing including a battery receiving portion configured to receive a removeable power tool battery pack and a motor housing; a brushless direct-current (BLDC) motor disposed within the motor housing, the motor including a stator and a rotor; a power switch circuit disposed between the battery receiving portion and the motor; and a controller that controls a switching operation of the power switch circuit to regulate a supply of power from the battery pack to the motor. At tool start-up, the applies a series of voltage pulses to the motor and measures a corresponding series of motor phase current values to identify an initial position of the rotor relative to the stator. Further, the controller identifies at least one of an impedance or a capacity of the battery pack as a function of the motor phase current values.

摘要： A permanent-magnet synchronous rotary electric machine for a self-propelled mobile device includes a stator having slots and a winding including at least three phases. The winding is of the type in which the number of turns N in the stator per phase is equal to the number of conductors in a slot, multiplied by the number P of pole pairs multiplied by the number of slots per pole and per phase, all divided by the number of parallel electrical paths of the conductors in a slot and/or divided by the square root of three if the winding is delta-coupled. The number of turns N per phase in the stator is between 9 and 20.
