Apparatus and method for controlling driving of linear motor
Jae-Mo Lee,Kyung-Bum Heo +1 more
TL;DR: In this paper, an apparatus and method for controlling driving of a linear motor is presented, which includes a detector that detects a current applied to a motor, a controller that outputs a control signal based on the detected current and a switch that varies the number of windings of the linear motor coil on the basis of the control signal.
Patent
Apparatus and method for controlling operation of reciprocating motor compressor
TL;DR: In this paper, an apparatus for controlling an operation of a reciprocating motor compressor includes a current integrator for integrating an alternating current applied to a motor of the compressor during each one cycle thereof; and a controller for differently controlling a firing angle of a triac during the positive phase and the firing angle during the negative phase of the AC voltage applied to the motor based on the integrated value of the current.
Patent
Driving control apparatus and method for linear compressor
TL;DR: In this paper, a control unit for detecting a current pushed amount of a piston when a TDC is detected as an inflection point of a phase difference between stroke and current, and applying a DC voltage applied to a linear motor based on the comparison result.
