Stepper motors are useful for relatively low-speed, intermediate-torque drive and positioning applications, particularly where accurate sub-revolution rotor position control is necessary. Motors of ...

This circuit automatically turns a motor cycle’s headlight on and off, independently of both the light and ignition switches, provided the battery is fully charged. The first stage uses the 22O ...

How does the NEC control your signaling and control wiring requirements? Today's industrial facilities use a host of control circuits for motor control, instrumentation signals, and plant shutdown ...

Overload devices protect motors, motor control equipment, and motor branch-circuit conductors against excessive heating due to motor overloads and failure to start, but not against overcurrent (e.g., ...

For the PDF version of this article, click here. Motor controllers used to power, stop and control the speed of a variety of motors must deal with a wide variety of surges due to switching events.

As previously mentioned, the feedback sensors include position sensors to track the rotor’s location, current sensors to measure the motor phase currents, voltage sensors to monitor the DC bus voltage ...

Groomed for use in small-motor control circuits, the HSF series surface-mount, surge resistor exploits a cylindrical design to aid heat dissipation and produce higher surge/pulse capabilities than ...

Faced with ever-increasing cost pressures and demands for improved performance, machine builders are actively seeking new automation solutions with improved cost/performance ratios. In response to ...
