Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

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 ...

En route to getting the off-the-peg DC-51 motor speed controller to better suit my small milling machine, I had a go at working out what the circuit is. Approx circuit of DC-51 motor speed controller ...

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 ...

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.

Another intriguing issue is whether circuits in the remaining frontal agranular cortex—presumably involved in more ‘cognitive’ aspects of motor control—are organized in the form of primary motor ...

All questions and answers are based on the 2011 NEC. Q. What is the Code rule for motor control circuit overcurrent protection? A. Motor control conductors that aren’t tapped from the branch circuit ...

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 ...

En route to getting the off-the-peg DC-51 motor speed controller to better suit my small milling machine, I had a go at working out what the circuit is. Approx circuit of DC-51 motor speed controller ...
