摘要： This disclosure describes at least embodiments of an aircraft monitoring system for an electric or hybrid airplane. The aircraft monitoring system can be constructed to enable the electric or hybrid aircraft to pass certification requirements relating to a safety risk analysis. The aircraft monitoring system can have different subsystems for monitoring and alerting of failures of components, such as a power source for powering an electric motor, of the electric or hybrid aircraft. The failures that pose a greater safety risk may be monitored and indicated by one or more subsystems without use of programmable components.

摘要： A dual actuated power pack (300) comprises a battery (104) and first (101) and second (102) electric motors, as well as a power generator (103). The first electric motor (101) is powered by the battery (104) and the second electric motor (102) by a grid (106). The first and second electric motors (101, 102) are mechanically coupled (108) with each other so that when said second electric motor (102) is powered, said second electric motor (102) actuates (109) said power generator (103) and said first electric motor (101) at the same time, whereupon the first electric motor (101) functions as a hi-power battery charger and recharge the battery (104) when said second electric motor (102) actuates (109) the power generator (103). When the second electric motor is not used, the first electric motor (101) is powered (104, 105), and the power generator (103) is actuated (108) by said first electric motor (101).

摘要： Provided are a motor driving control apparatus and a steering system. The motor driving control apparatus includes an inverter circuit configured to supply a motor driving power to a motor for steering assist, a motor control circuit configured to control operation of the inverter circuit according to whether a control power is input, and a switch circuit configured to control whether to input the control power to the motor control circuit in response to a control signal. When a failure occurs inside or outside the steering system, the apparatus and steering system can immediately stop motor driving for steering assist and thereby prevent a vehicle accident.

摘要： A motor drive apparatus drives and controls a plurality of motors that rotate a common drive shaft. The motor drive apparatus includes a motor drive hardware processor that outputs equal drive power to each of the plurality of motors, and manipulates the drive power with a rotational speed detection signal of any one of the plurality of motors as a feedback signal. The feedback signal is switched based on conditions such as responsiveness and efficiency.

摘要： A half-bridge inverter comprised of upper and lower switches can be placed in linear motor track sections to alternately connect a common point of all drive coils to a full-bus DC power rail (“full-bus”) and a DC reference, according to PWM command signals, functioning as a “virtual mid-bus” to allow bi-directional flow of a sum of currents of all drive coils in the section. Separate upper and lower drive switches of the half-bridge inverters that are also connected to drive the drive coils can then be controlled, according to separate PWM command signals, to synchronize their PWM cycles and duty cycle commands with respect to the virtual mid-bus at times when a mover is not present, resulting in zero voltage across the drive coils, or command different duty cycles with respect to the virtual mid-bus when a mover is present, resulting in a desired voltage across the drive coils. The desired voltage can produce a current in the drive coils to electromagnetically propel the mover.
