摘要:
A hybrid vehicle includes an ECU (300) and the ECU (300) is configured to execute inverterless traveling control. The inverterless traveling control is control for causing the vehicle (1) to travel by placing an inverter (221, 222) in gate cut-off states, and driving an engine (100). The ECU (300) interrupts motor current (IM1) flowing between a motor-generator (10) and a battery (150), when the shift range is a range other than forward ranges, during the inverterless traveling control. In such a vehicle, a method for performing the above-defined inverterless traveling control, in which the current flowing between the motor-generator (10) and the battery (150) is interrupted when a shift range other than a forward range is selected, during the inverterless traveling control (S180,S280,S430,S530).
摘要:
A motor drive system 10-1 for a railway vehicle is capable of reducing the weight of wiring, electromagnetic noise, and manufacturing cost. The motor drive system includes an inverter 11. The inverter is configured to control a motor 13-1 and is divided into at least two separate inverter units that are arranged integrally with the motor.
摘要:
An active attenuation system for a DC motor (11) which yields global vibration reduction of slot or other motor induced tonals at the plate on which the motor is mounted without modifying the construction of the motor. The system comprises one or more vibration sensors (13), a signal synchronized to the slot rate or other motor induced tonal rate, an electronic adaptive controller (12) and the means to inject the control signal into the motor field and/or armature current.
