PROBLEM TO BE SOLVED: To provide a further gearing assembly that rotatably connects a prime mover with a motor-generator.SOLUTION: This mechanical transmission assembly receives an input rotating at a first rotational speed and provides an output rotating at a second rotational speed. The mechanical transmission 56 selectively adjusts the second rotational speed. The input is provided by a prime mover. The output is provided to a hydraulic pump assembly that rotatably drives a motor-generator 50. A method of driving the motor-generator 50 with a prime mover comprises: driving a transmission 56 with an input shaft 70 from a prime mover. The input shaft 70 rotates at a first rotational speed. The method drives a hydraulic pump 58 with a first output shaft 72 from the mechanical transmission 56, The shaft 72 rotates at a second rotational speed. The method drives the motor-generator 50 with the hydraulic pump 58; The method selectively adjusts the transmission 56 so that the first rotational speed is different from the second rotational speed.

PROBLEM TO BE SOLVED: To provide a wind turbine with articulated blades whose conversion efficiency is improved.SOLUTION: The wind turbine 10A includes: inboard blades 12A, 12B, 12C; outboard blades 14A, 14B, 14C; a hub 16; a winch 18; a drive device 20; cables 22A, 22B, 22C; pulleys 24A, 24B, 24C; elbows 26A, 26B, 26C; and spring loaded hinges 28A, 28B, 28C. The outboard blades pivotably connected to the inboard blades are driven with respect ot the inboard blades by cables so that swept angles Ψ, Ψ, Ψare varied. Thus, the conversion efficiency for wind turbine is optimized in view of wind conditions, etc. In low wind conditions, the outboard blades achieve maximum conversion efficiency by extending the swept angles to a position up to 180° between blades. In higher wind conditions, the outboard blades drive the inboard blades up to 180° or less of the swept angles. Consequently, the wind turbine 10A is not required to be shut down even in higher wind conditions.

PROBLEM TO BE SOLVED: To provide a starter for an auxiliary power source, which damps torque shock at clutch engagement and reduces the damage and breakage of a starter shaft.SOLUTION: A starter for an auxiliary power source includes a direct current motor operably connectable to an auxiliary power source. A clutch is arranged to the direct current motor in an electrically parallel relationship and configured to operably connect the motor to the auxiliary power source when engaged, the motor and the clutch powered by a common input line. A time delay switching element is located and configured to delay power delivery to the direct current motor thus providing for full engagement of the clutch prior to initiation of rotation of the motor.

PROBLEM TO BE SOLVED: To provide a barrier and a seal which efficiently separate a volatile environment and an electronic device so that an electric spark and oxygen do not interact.SOLUTION: A motor 100 includes a rotor 170 configured to be exposed to a volatile environment 105 and an electronic device 135 for rotating the rotor 170. A housing 110 includes a cylindrical portion 120 closed by an end portion 125, and the electronic device 135 is housed in the cylindrical portion 120. The electronic device 135 is separated from the volatile environment by a non-metallic barrier 175. In the housing 110, O-rings 145 held by four groups of radial-direction grooves 140 serve as a flexible seal so as to protect a ceramic material of the non-metallic barrier 175 from deflection in the motor 100 due to bending or twisting and from vibrations and impact that may break a barrier made of glass in a firm attachment structure.
