摘要： Method and system for controlling the start of a permanent magnet machine are provided. The method allows to assign a parameter value indicative of an estimated initial rotor position of the machine. The method further allows to energize the machine with a level of current being sufficiently high to start rotor motion in a desired direction in the event the initial rotor position estimate is sufficiently close to the actual rotor position of the machine. A sensing action allows to sense whether any incremental changes in rotor position occur in response to the energizing action. In the event no changes in rotor position are sensed, the method allows to incrementally adjust the estimated rotor position by a first set of angular values until changes in rotor position are sensed. In the event changes in rotor position are sensed, the method allows to provide a rotor alignment signal as rotor motion continues. The alignment signal allows to align the estimated rotor position relative to the actual rotor position. This alignment action allows for operating the machine over a wide speed range.

摘要： A controller for power devices which is not required to individually insulate high and low potential portions and to include an insulated power supply is disclosed. An external controller (6) is connected to a second internal control circuit (4) which is in turn connected to a level shift circuit (5) and a gate electrode of a transistor (Q2). Power supply voltage (V1) is applied to the second internal control circuit (4) for operation thereof. The level shift circuit (5) is connected to a first internal control circuit (3) which is in turn connected to a gate electrode of a transistor (Q1) and a charge pump circuit (7). Control of a first semiconductor circuit is made through the level shift means in response to an input signal generated on the basis of a second main power supply potential, thereby achieving increased responsiveness of the power devices to a control signal and improved integration.

摘要： An electronic circuit and software control methodology tracks motor position in a motor drive system. High power consumption position transducers, such as inductive sensors or optical encoders, can be controlled in a variable active duty cycle mode to reduce power and yet maintain motor position information while the main power is off. A lower power battery backup circuit is implemented as a secondary power source, and is automatically brought in operation when the main power supply is disabled. A dedicated control circuit operates during AC power outages, and the circuit average power can be controlled to a minimal rate, based on the rate of change of motor position. The motor can be externally driven, up to a defined limit speed, without losing its actual position information.

摘要： A method of compensating for abrupt load changes in an anti-pinch window control system (300) includes measuring an instantaneous torque value (412) of a window lift mechanism (200) and calculating a pinch factor (430) based on the instantaneous torque value (412) and a stored torque value (424). A pinch threshold (308) is then adjusted based on the pinch factor (430) to define a modified pinch threshold (432). Stored torque value (424) includes stored torque values from sections of travel (406) of window (104), stored downstroke torque values (428) and stored upstroke torque values (426).

摘要： The presence of an object in the path of an automotive vehicle window is detected. This is accomplished by sensing or observing a system variable, such as speed or motor current, and comparing this measured value to a predicted limit value of the system variable which is based upon the behavior of the system variable when there is no object present. The values are compared over predetermined time intervals and if the measured value falls out of the predicted limit value of the system variable in a direction that indicates an obstruction, then a control system detects the presence of an object and reacts accordingly by stopping or reversing the drive motor of the vehicle window.

摘要： The apparatus comprises a motor, a motor driver, a pulse generator, an MCU incorporating a memory, and an open/close switch. The MCU compares the motor load torque detected at the time of opening or closing the window, with a reference value stored in the memory; when the torque considerably exceeds the reference value, it concludes that there is a foreign object caught in the window and stops or reverses the motor and inactivates the function of foreign object detection until there is no transitional torque fluctuation in the transitional period from a start of the motor. The MCU compares the torque variation per unit time with a permissible variation range stored in the memory; when the number of successive torques which fall within the permissible variation range reaches a maximum permissible number of such successive torques stored in the memory, it activates the function of foreign object detection.

摘要： An AC motor is utilized to drive a closure on a vehicle. The use of the AC motor provides valuable benefits with regard to cost and size. Further, a three-phase AC motor may be utilized, and the pulses in its power supply monitored to determine an obstruction in the path of the closure. Frequency control may also be utilized to provide optimum control of the drive of the component at both start-up and stop.

摘要： A winding end cap assembly for an electric machine with a stator and stator poles includes first and second end caps that are connected to opposite axial end surfaces of one of the stator poles. First and second inner winding retainer sections extend axially to connect an inner end of the first end cap to an inner end of the second end cap. The first and second end caps include an outer section, an inner section and a hub section that connects the outer section to the inner section. The first and second end caps and the first and second inner winding retainer sections define a continuous annular channel that receives and retains winding wire. First and second outer retainer sections connect the first and second end caps adjacent to the outer sections or the hub sections of the first and second end caps.
