Applications requiring variable speed control, precision performance with low torque ripple, and high power in a compact, 1.73'' in diameter package are said to represent the primary market for NT ...

The speed of a DC motor is directly proportional to the voltage applied across its terminals. The speed of a DC motor is directly proportional to the voltage applied across its terminals. This project ...

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

UPM and WPM variable-speed dc drives have been redesigned to comply with Europe’s RoHS directive. These dc controls are suitable for applications requiring single-direction speed pot controls such as ...

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 ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

Prior to the advent of the adjustable-speed drive (ASD), the polyphase induction motor operated as a constant-speed motor. Figure 1 shows the well-known torque and current curves versus speed for the ...

The Separator 3250 motor-driven ribbon cable separator is now available with a variable speed (dc) drive option, providing separation speeds of from 0 to 20 in./minute the variable speed option is ...
