A design of winch actuator speed control actuator on the gamma detection device geophysics logging

The detection device consists of a detection system, data acquisition system and winch control system actuators. The winch speed actuator controller is for controlling the speed of detector 6 meters/minute and capable of carrying 20 kg load as far as 500 meters into the under ground using an electric motor. The purpose of this design is to determine and to select the electric motor according to speed control of winch actuator desired. The method of the design is using these used data to determine the motor power, motor rotation, and speed winch actuator used. A DC series motor of 1/20 HP, 24 V, 1140 RPM is the motor is provided with settings to the motor power supply voltage from 12 V up to 24 V and resistance from 0 Ω up to 12 Ω. The resistance is connected in series with motor yoke. (author)
