Until the advent of variable speed drives (VSDs), torsional fatigue failures were rare: Equipment designers could anticipate operating speeds and excitation frequencies and engi-neer around them. The purpose of a VSD is to allow operation at a wide range of speeds. That, unfortunately, has led to many motor and driven-shaft failures due to torsional-fatigue factors. While the most common ...

A variable speed drive system consists of a motor, a drive and sometimes also a transformer. When talking about drives, this white paper refers to the entire system. VSDs control the speed and/or torque of AC motors by adjusting the frequency and voltage of the motor supply. Using a drive, the speed of the motor can be regulated to match the exact needs of the process. As a result, the motor ...

In its simplest form, a rolling mill (Fig 1) consists of two driven rolls in a mill stand with a screw down. The work piece to be rolled is passed through the rotating rolls to get the desired shape. Fig 1 A simple rolling mill. But in practice rolling mills are not that simple. They are quite complicated and they are of several types. Though all the rolling mills utilize the same principle of ...

In rolling mill drives, often 200-300% of the base speed is used. The mechanical strength of the rotor limits the maximum speed of the motor. Fig. 1: SPWM carrier-sine input & 2-level PWM output. An embedded microprocessor governs the overall operation of the VFD controller. Basic programming of the microprocessor is provided as user-inaccessible firmware. User programming of display, variable ...

A Variable Speed Drive (VSD) consists of a Motor and some form of controller. Early electric VSDs consisted of AC and DC motors combinations which were used as rotating controllers. The first electronic controllers used Thyristor (SCR) Rectifiers which controlled the voltage, and therefore the speed of DC motors. These DC VSDs are still widely used and offer very sophisticated control ...

Mechanical linear actuators are not typically used in faster-speed applications and are usually seen in hoists, chain drives, and belt drives. Car jacks and jackscrews also use these types. Hydraulic actuators are typically made for high-force, high-speed uses, but they can be found in more familiar products like hydraulic carjacks as well. Pneumatic linear actuators can be found in things ...

Get the speed ratio by dividing the speed in RPM of the power shaft by the speed in RPM of the load shaft. Assume a power shaft pulley size of 4 inches. This is generally a good size for efficient belt operation. Multiply by the speed ratio. The result will give the load shaft pulley size. A result less than twelve inches is acceptable. Otherwise, reduce the power shaft pulley size to 3 inches ...
