摘要： A vertical axis windmill with a deceleration control system includes: a stationary shaft, a rotary shaft rotatably sleeved onto the stationary shaft, plural blades fixed to the rotary shaft, and a generator disposed between the stationary shaft and the rotary shaft. The deceleration control system includes a damping plate, a magnetic-force generating unit, a rectifier, and a control unit. The magnetic-force generating unit generates an eddy current to produce a damping effect. The rectifier converts AC voltage outputted from the generator into DC voltage. The control unit is coupled between the rectifier and the magnetic-force generating unit and sets a conduction level. When the DC voltage is lower than the conduction level, the rectifier and the magnetic-force generating unit are electrically disconnected from each other, and when the DC voltage is greater than the conduction level, the rectifier and the magnetic-force generating unit are electrically connected to each other.

摘要： A motor controller for an electric motor having a stator and a rotor. The motor controller includes a power input for receiving AC power from a power source; a control input for receiving a control signal from a control; and circuitry for switching power from the power source to the electric motor in response to the control signal. The circuitry is operable to: apply a driving waveform to the stator to cause rotation of the rotor; remove the driving waveform from the stator to cause the rotor to coast and eventually stop; apply a stop detection waveform to the stator while the rotor is coasting, wherein the stop detection waveform induces a waveform on the rotor which in turn induces a waveform back to the stator while the rotor is rotating; and monitor the stator to detect a characteristic of the waveform induced back to the stator to detect when the rotor has substantially stopped rotating.

摘要： A PWM signal generation unit generates a PWM signal to drive a motor, based on a current value of the motor sampled by a current value sampling unit, a position or speed of the motor sampled by a motor sampling unit, and a position or speed of a driven object sampled by a driven object sampling unit. An operation stop unit stops the operation of any one of the motor sampling unit and the driven object sampling unit depending on the power stored in the DC link part and power to which the control power source can supply when the alternating-current power source fails.

摘要： In the case of a method for automatically controlling an electrohydraulic pressing tool, in particular for producing pipe connections, to actuate the pressing tool a hydraulic piston is moved, in that fluid is pumped into a hydraulic cylinder by a hydraulic pump driven by an electric motor. When a limiting pressure in the hydraulic cylinder is reached, a pressure relief valve opens, and so the hydraulic fluid can flow into a reservoir. With the aid of a control device, a current drop at the motor is detected when the valve opens. The electric motor is switched off when the current falls by a predetermined value (ΔI) and/or decreases over a predetermined time period (Δt) after reaching a limiting current.
