摘要： A Digital Programmable Motor Overload Protector includes a base module and a detachable, removable user interface module interfaced through a serial communications link. The base module provides motor overload analysis through a programmable Digital Signal Processor (DSP) which digitizes real time motor operating conditions, comparing stored user trip and alarm levels against these conditions, communicating the results to the detachable user interface and a multi-drop communications link using the industry standard MODBUS RTU protocol to a facility's automation system. Motor operating conditions, user settings, override conditions, pass events, and resettable parameters are available through the password protected removable user interface module or the multi-drop communications interface.

摘要： The present invention provides a system for disengaging a motor and preventing dynamic braking current loops. The system includes a power circuit, a gate driver circuit, and unidirectional switches attached to each motor winding. Unidirectional switches such as field effect transistors (FETs) can provide current blocking in only one direction when not conducting. Unidirectional blocking according to the present invention is sufficient for preventing the undesirable dynamic braking current loops. The approach of this invention requires N unidirectional switches, where N is the number of motor windings. Thus, on a 3 phase motor, three unidirectional switches are used, each being in series with one on the motor windings.

摘要： The variable valve timing controller has an electric motor which rotates a phase converter. When the electric motor is locked for some reason, the over-lord more than the predetermined value is applied to a motor shaft and the phase converter. In such a case, a pin connecting the motor shaft with the phase converter is sheared at a notch. Thus, a cam shaft and the phase converter were not locked, and breakage of a motor housing is prevented.

摘要： A control system and method predicts the occurrence of elevated temperatures in an electric motor 12 used to operate a window closure system. The motor 12 includes an output 14 that is operably coupled to a window component 16. A controller 20 monitors at least one motor characteristic, such as motor activation occurrence or duration of activation, over a period of time and generates an output signal 22. The controller 20 prohibits operation of the motor 12 when the output signal 22 exceeds a predetermined limit.

摘要： A motor-driven curtain assembly includes a drive shaft mounted rotatably in a top rail, a motor for driving rotatably the drive shaft, and a curtain unit coupled to the drive shaft for movement between closed and open positions. A motor-control device includes a driving circuit for enabling rotation of the motor in one of positive and negative directions under the control of a control unit, a current limiting circuit for limiting current flow from an external power source to the driving circuit when the motor is subjected to an increase in load resistance, and an over load detector for generating a control signal that is indicative of the amount of current flowing from the current limiting circuit to the driving circuit and that is provided to the control unit, thereby enabling the control unit to deactivate the driving circuit for stopping operation of the motor when overloading of the motor occurs.

摘要： Disclosed is an improved system and method for sensing both hard and soft obstructions for a movable panel such as a sunroof. A dual detection scheme is employing that includes an optical sensing as the primary means and electronic sensing of motor current as a secondary means. The secondary means utilizes system empirical precharacterization, fast processing algorithms, motor parameter monitoring including both current sensing and sensorless electronic motor current commutation pulse sensing, and controller memory, to adaptively modify electronic obstacle detection thresholds in real time without the use of templates and cycle averaging techniques.

摘要： A drive system for a covering device, which can be rolled up or folded, for motor vehicles is equipped with a control device. The control device has a current sensor for detecting the current applied to an electric motor of the drive system in the course of moving the covering device. The control system measures a current parameter at the start of the movement of the covering device and switches off the current to the motor as soon as switch-off criteria derived from the current values measured at the start of the movement have been reached.

摘要： A window actuation assembly for a vehicle which is structured to automatically lower at least one, but preferably all of the windows of a vehicle in the event that a vehicle becomes partially or totally submerged in a body of water and regardless if the orientation of the vehicle, is up-right, inverted, on its side, etc. One or more fluid sensors are located strategically throughout the various portions of the vehicle and are specifically structured activate a drive assembly for the lowering of the windows upon sensing a predetermined amount of water within an associated proximity of the vehicle, to the extent that the one or more sensors are themselves at least partially submerged. The sensors are further structured not to be activated in the unlikely event that liquid inadvertently is spilled upon or otherwise applied thereto. The one or more sensors may be associated with a single drive assembly and/or independent drive assemblies associated with each of the windows such that only one, or more preferably all of the windows may be lowered in an emergency, submerged condition of the vehicle. The windows may be restricted from being raised into the normally closed position once they have been lowered under emergency circumstances, in order to prevent inadvertent closing of the windows by an occupant of the vehicle suffering from injury or being otherwise disoriented because of the emergency.
