Method And Apparatus For Controlling Stepmotor Mechanical Drives
US Patent:
4888541, Dec 19, 1989
Filed:
Oct 23, 1987
Appl. No.:
7/113176
Inventors:
Jack Russell - Libertyville IL
International Classification:
H02P 800
US Classification:
318696
Abstract:
A method and apparatus for controlling stepmotors having a broad range of applications including fuel control for gas-turbine engines, and operating powered automatically controlled doors for mass transit vehicles is disclosed. Step motor control through analysis of the motor winding currents during application of controlled voltage pulse provides a basis for evaluating shaft torque conditions at the motor load without return or feedback signals from the driven load. This type of current analysis utilizing digital techniques provides a convenient, reliable, and economical means for detecting stepmotor output shaft position and loading. Detection and recognition of output shaft load or drive requirements is then utilized in a control system wherein functional requirements of the system including motion and/or torque requirements of the shaft output load can be controlled in accordance with desired system operation. A control algorithm based on earlier determined stepper current characteristics is utilized in evaluating any particular stepper motor at any time during operation. Digital techniques utilize the aforementioned algorithm sample stepper motor current, measure and detect predetermined time based values of motor current, thereby providing a basis for evaluating stepper motor shaft loading during each step corresponding to and initiated by a voltage pulse.
Electronic Control System
US Patent:
4147939, Apr 3, 1979
Filed:
Jul 18, 1977
Appl. No.:
5/816257
Inventors:
Jack A. Russell - Libertyville IL
International Classification:
H03K 1700
US Classification:
307116
Abstract:
This invention is concerned with an electronic control system that uses a common two wire lead with a plurality of detector units connected in parallel thereto in order to control a plurality of electrical loads. The common two wire lead is connected to a single master controller. Control modules RF matched individually to each detector are mounted on the controller and move the loads coupled to each detector. This system finds great acceptance in regulating solenoid motors such as found in model railroad train layouts.
Traction Load Meter System
US Patent:
4804910, Feb 14, 1989
Filed:
Feb 14, 1986
Appl. No.:
6/829827
Inventors:
Jack A. Russell - Libertyville IL
Assignee:
Vapor Corporation - Chicago IL
International Classification:
G01R 1918
G08B 2100
G06F 1548
G08B 2100
G06F 1548
US Classification:
324120
Abstract:
A traction load meter system for displaying information concerning the amount of current energizing electric motors which drive a locomotive. These motors have power and braking modes and have a continuous current rating. The system includes a current-to-frequency converter for providing an output signal having a frequency corresponding to the amount of current drawn by the motors. Electronic logic circuitry is included for receiving this output signal and being responsive thereto to provide outputs indicating whether the locomotive is in the power or braking mode, the amount of current being drawn, whether this amount is above the continuous rated current for the motors, and the period of time the above-rated condition has existed. Additionally, the meter system includes a display panel connected to the logic circuitry and adapted to be mounted in a cab of the locomotive for displaying to the engineer the aforementioned outputs of the logic circuitry.
