摘要： Multiphase electromagnetic machines, such as free-piston engines or compressors, may require, or supply, a pulsed power profile from or to a DC bus, respectively. The pulsed power profile may include relatively large fluctuations in instantaneous power. Sourcing, sinking, or otherwise exchanging power with an AC grid, via an inverter, may be accomplished by using an energy storage device and a DC-DC converter coupled to a DC bus. The energy storage device may aid in smoothing the pulsed power profile, while the DC-DC converter may aid in reducing fluctuations in voltage across a DC bus due to energy storage in the energy storage device.

摘要： An actuation system is proposed for an optical system, comprising a voice coil motor for actuating the optical system, the voice coil motor comprising a magnet and an electric coil, a position measuring unit for measuring the position of the electric coil and providing a position feedback signal, and a control unit for closed loop control of the position of the optical system based on a target position and the position feedback signal, used for generating a drive signal for the electric coil. According to the disclosure, a ferromagnetic element is arranged in proximity to the electric coil so that the inductance of the electric coil depends on its position. Further, the position-measuring unit measures the inductance of the electric coil and determines the position of the electric coil based on the determined inductance.

摘要： An electric linear motion actuator includes an electric motor, a motion converting mechanism that converts the rotational motion of the electric motor into a linear motion of a linear moving member, a load sensor that detects the magnitude of the load applied to the brake disk from the linear moving member, and a controller that performs feedback control on the electric motor based on the difference between the load detected by the load sensor and a load command value. The controller reduces the number of revolutions of the electric motor when the linear moving member moves into a predetermined zone immediately before the position where the clearance between the linear moving member and the brake disk becomes zero.

摘要： A dynamic linear motor is controlled by determining a relative proximity of a moving rotor of the linear motor to a fixed stator segment of the linear motor using a current location of the moving rotor. A current driving characteristic of the linear motor at the current location of the moving rotor is determined. Settings for the fixed stator segment when the moving rotor reaches the fixed stator segment are identified based on the current driving characteristic. The fixed stator segment is driven based on the settings when the moving rotor reaches the fixed stator segment.
