Motion Control

Controlling Devices Using the Ear as an Output Source

This method creates a hands-free way of controlling devices such as medical equipment, wheelchairs, computers, and cell phones.Current methods of device control include joysticks, which involve using one or both hands, external microphones that are cumbersome and pick up ambient noise, and external arrays that are also cumbersome and can restrict a user’s movement. Additionally, the external microphone and array options do not provide a high level of accuracy in certain situations.

All Motors are Stepping Motors

In 1938, General Electric began producing a two-phase synchronous induction motor which, at 60 Hz, ran at 75 RPM. The low speed resulted from using a different number of rotors to stator poles or teeth, which made the motor a good bi-directional control motor. This motor was used by Superior Electric Company of Bristol, CT, to run power driven autotransformers used to dim lights in auditoriums and similar applications. General Electric ceased producing this motor in the mid 1950’s due to slow sales.

Intelligent Control Increases Motion System ROI

The economic realities of the industrial marketplace are driving machine builders and integrators to get creative and build more intelligence into their machines in order to increase productivity and lower lifecycle cost. This is done by minimizing time to communicate with the motion controller, and by setting up and optimizing the closed-loop controls that squeezes the last few unneeded time cycles from a machine operation. Therefore, by looking at how a motion controller connects, controls, and can optimize a system, the best performance per dollar invested can often be accomplished.

Intelligent Motor Control ICs Simplify System Design

A new category of IC called an intelligent motor controller (IMC) is evolving that simplifies the task of designing high performance motor control drives. IMCs are dedicated, highspeed ICs that control multi-phase motors such as brushless DC and AC induction motors, and provide sophisticated control features required by today’s energy-efficient applications such as variable speed, flux vector control, and even sensorless control.
