Adjustable speed drive, also known as variable-speed drive, describes equipment used to control the speed of machinery. Many industrial processes such as assembly lines must operate at different speeds for different products. Where process conditions demand adjustment of flow from a pump or fan, varying the speed of the drive may save energy compared with other techniques for flow control. Where speeds .

How to Vary the Speed on an AC Electric Motor. Use a variable voltage transformer to change the voltage supplied to the main winding if you desire a high slip, reduced voltage speed control, which is more efficient. The variable voltage transformer has low losses compared with the variable resistor.

This electric chain hoist has variable lifting speeds ranging from 1 – 26 FPM. That means you will have ultimate control and precision while operating. Use the easy to turn dial to adjust the speed even while your hoist is in motion. Versatile. The Starke Variable Speed VS Electric Chain Hoist can be easily added to any existing workstation.

Nov 25, 2015 · A variable speed drive (also known as a VSD, variable frequency drive, VFD, adjustable speed drive, inverter, converter or simply, 'a drive') is a device which is used to control the speed or torque generated by an electric motor.

i am trying to 'automate' the control of an electric drill motor that im taking from a garden variety Variable Speed drill (from Harbor Freight) it has a universal AC motor which I basically undertand and a DPDT switch to reverse direction and a triac citcuit to vary speed . Question 1 . i see 4 wires going to the 'field/Stator coil(s)'.

VARIABLE SPEED ELECTRIC CHAIN HOIST Hoist offers Exceptional Value for Industrial Lifting applications. Variable speed hoist makes it easier and faster to lift products, saving maintenance, repair and downtime costs over their lifetime. High-torque ½ HP motor includes an auto-brake mechanism that stops and holds the load, even with loss of power.

Variable speed ECM motors if programmed and set properly improve system temperature, humidity, and capacity. Variable speed ECM motors can vary the speed based on input from a control board. Variable speed ECM motors enhance the efficiency of an HVAC system. Variable speed ECM motors offers slow start or soft start capabilities.

Mar 07, 2012 · Can I put a variable speed control on any motor? I have made a work fan for outside and the motor I had works but I dont want it wide open all the time, and the motor is just one speed (fast!!!) is there some kind of variable control I can put on or inline with the electrical to adjust the voltage to where it will go slower? I wasnt sure if you...

Aug 14, 2015 · The speed of any AC motor is dependent on the applied frequency. However, some AC motors are just not suitable for variable speed operation. Single-phase motors (for reasons I won't go into here. Mostly it has to do with how single-phase motors START. Once they're running, change the frequency, change the speed.) are just not good candidates.

The low speed setting may be set to 1.5 feet per minute without sacing the normal lift speed of the electric hoist to reduce die impact damage and shock loading conditions. The variable speed hoist feature permits fine mold positioning without continuous hoist jogging.
