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 ...

These variable speed drives (VSDs) were developed to avoid the additional equipment and maintenance requirements associated ...

Discover how 24V BLDC motors enhance HVAC efficiency and reduce maintenance costs. Learn key selection tips on torque, voltage, sizing, and system integration to ensure reliable, quiet, and ...

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 ...

The low-voltage variable speed drive (VSD) allows variable control instead of fixed-speed operation. These days, VSDs can ...

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 ...

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 ...

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 ...

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 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 ...
