Motion Controller Basics
are specified in terms of the total distance, slew speed, and acceleration rate. Because the motor position follows the commanded position, the motion profile controls the motion path and rate. In addition to these basic tasks, an advanced motion controller may perform high-level functions

Motor Starters
during both starting and running, thus the main contactor is closed when the motor is operating. The dc winding of the rotor is energized by the field contactor as the motor approaches synchronous speed. Two normally open poles on the field contactor make the connection for dc excitation, and one

Mathematics of Electronic Motor Control
brush motor, which is a single phase device, generating this is done by a mechanical commutator with brushes. In a brushless DC motor, it must be done by the external controller. Figure 1 shows two kinds of force that are generated by the magnetic field interactions. They are known as the Q (quadrature

Step Motor Automates Innovative Camera
a Hasselblad camera with a cordless drill moving the film. Eventually, a brushed dc motor replaced the drill. A simple potentiometer with a bicycle speedometer controlled the motor and set its rpm. One problem: Subtle changes in motor speed left vertical lines on the film. A 1-lb flywheel attached

Brushed-dc and Piezo Motors Combine for Precise Position
transport using a geared dc motor with the fine adjustment handled by a high-precision piezomotor. The Faulhaber Group, Germany, supplied both motors for the design and worked with Feinmess Dresden to optimize the drive controller so both motors perform their specific tasks in harmony. Ultrasmall-scale

Integrated motor and drive includes motion controls
by adding a complete motion controller. The MDrive42AC Plus consists of a NEMA-42 hightorque brushless motor with fully integrated drive and control electronics. The company says the control delivers high-positioning accuracy, stability at low speeds, no dithering at zero speed, high starting torque
