Title: Controller for motor
Inventor: MUKAI CHUKICHI
IPC: H02P27/06
Filed: 1988-11-25
Abstract: PURPOSE:To increase a load current in a low frequency range by invalidating the operation of stroke preventing means when the output frequency of an inverter is a predetermined frequency or less. CONSTITUTION:Power from an AC power source is supplied to an induction motor IM through a converter/inverter to control rotation. The control of the inverter is conducted by a CPU 3. Since accelerating/decelerating time is not matched to load inertia at the time of accelerating/decelerating so that a load voltage might rise, a stroke preventing function is operated to wait the follow-up of the load. This function is not operated when the present frequency is lower than a predetermined value. Thus, a compensating current can flow to obtain a predetermined torque in a low frequency operating range.

IPC: F04D13/04
Filed: 1994-12-05
Abstract: PURPOSE: To avoid shutting off of an engine during flight by preventing mixing of hydraulic fluid and blocking of a drain and providing a shaft seal system between a pump and a gear box. CONSTITUTION: An arclike chamber 56 is formed in a flangelike end member 22 of a pump, which has an annular shoulder 58 receiving a baffle 60 having a plate shape. The baffle 60 is engaged with a seal 62 arranged in a groove 64 provided in the end member 22 of the pump. The baffle 60 has a plurality of grooves 68 in the radial direction on its flat face, which form a passage P when they are arranged on the end member 22. When hydraulic fluid leaks across an inner seal 52, leaking hydraulic fluid passes the passage P formed by this groove and enters the arclike chamber 56. The hydraulic fluid collected in the chamber 56 is discharged out of an aircraft through a drip drain system of the aircraft. Consequently, it is possible to prevent mixing of hydraulic fluid which leaks across a seal of the pump and a gear box and has no interchangeability.
