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 ...

DC Motors were king in industry up until the late 1980s; These motors were popular because they were able to run to a variable speed setpoint, and they could run at full torque from stall to base ...

In addition to industrial applications of variable-speed motor drives, the home appliance market is another major area where three-phase pulse width modulated (PWM) motor control drives are finding ...

Special algorithms make ac induction motors respond like variable-speed dc motors for fast PID control. Synchronous dc motors often top the field in high-performance motor controls. This group of ...

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 ...

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 ...

When Tesla first introduced the 3-phase alternating current (AC) induction motor in 1888, he knew that his invention was more efficient and reliable than Edison's direct current (DC) motor. However, ...

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 ...

Variable-speed blowers on indoor units can enhance the comfort and efficiency of residential HVAC systems, but most homeowner customers won’t be aware of those benefits unless you explain them. A few ...

Electrical equipment often has at least one motor used to rotate or displace an object from its initial position. There are a variety of motor types available in the market, including induction motors ...

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 ...
