A system, method, and device for protecting an induction motor are disclosed. The exemplary system may have a module for determining the current drawn by the motor and a module for determining the state of the motor. The system may calcu... M Bilac,C Fan,M Golod - US 被引量: 6发表...
The control parameter is derived from the operating current drawn by the electric motor (5) during seat adjustment.WEISHAUPT, WILLIHOPPE, GERDMENZEL, WERNERFRICKE, MICHAEL
When the electric motor reaches one of its extreme positions, the sense component senses an increase in the current drawn by the motor. The sense component then signals the control component to cause the interrupt component to interrupt the current and stop the motor. In one embodiment of this...
Current.. forced or drawn? Hi all I'm a bit confused by DC current (possibly AC too if its the same). On many DC power supplies it will state the...
81/467, 469; 388/937; Senses the amount of current by the electrical motor and 318/17, 632 generates a signal quantifying the amount of current drawn by the motor so that the amount of current drawn can be 56) References Cited re-Supplied together with a target Speed Signal through a ...
An AC power amplifier is disclosed for amplifying an AC input signal while limiting the current drawn by the amplifier. The amplifier includes at least one transistor having an input circuit for receiving an AC input signal as well as a DC bias voltage and an output circuit connected to the ...
Apparatus and method for reducing the current drawn during starting of a single-phase AC asynchronous motorCurrent consumption during the starting process of a single-phase a.c. asynchronous motor is reduced by an apparatus including a thermistor which can be mounted in series with the main ...
