摘要： A motor-driven compressor used as a compressor or high-pressure gas generator for a refrigerating cycle, in which the output torque of the electric motor for driving the compressor is controlled so as to make the output torque agree with the load torque required for performing compression in any revolutional angular position of the driving main shaft to thereby reduce revolutional torsional vibrations caused by disagreement between the load torque and the output torque.

摘要： A torque control unit rotates a motor machine having a motor element and a load element. The load element is coupled to the motor element via a rotational main shaft and driven to rotate by the motor element. Rotational acceleration at each rotation angle during one revolution of the rotational main shaft is detected and fed back. An electromagnetic torque of the motor element is controlled so that a difference between the electromagnetic torque of the motor element and a load torque of the load element may become zero at each rotation angle of the rotational main shaft.

摘要： A reduction starter employing a planetary gear type reduction gear mechanism having an outer ring gear displaceable radially of a common axis of a central sun gear and an output shaft carrying planet gears for revolution about the common axis. The outer ring gear is formed by an internally toothed ring gear elastically deformable to assure uniform distribution of load torque to all planet gears. The tooth root bending stress of the ring gear is substantially equalized to the outer periphery bending stress thereof to improve the load performance of the planetary gear type reduction gear mechanism and thus reduce the size and weight of the starter. The outer ring gear has an outer rim of a radial thickness t and a plurality of radially inwardly extending teeth each having a height h. The rim thickness t is determined to'fall with a range of from +.ltoreq.0.8 h to +.gtoreq.0.4 h.

摘要： The compressor is characterized by a high pressure port provided in a rear plate at a position that the bottom portion of a vane groove of a vane which reaches a delivery port contacts the high pressure port, and low pressure ports provided, independently of the high pressure port, in the front and rear plates at positions so that the low pressure ports communicate with the high pressure port through the bottom portion of the vane groove of the vane between the low and high pressure ports only when the center of said vane groove is disposed between the high and low pressure ports so that the high pressure is fed intermittently to the low pressure port. In a region of rotation of the rotor where vane-tip pressing force is small, a high pressure from the high pressure port is applied to vane grooves as vane back pressure, and in the other region a relatively low pressure is applied thereto from the low pressure ports.
