Here are some basic equations that will help you understand the relationship between hp, torque, and speed. hp = (Torque x Speed)/5250 (eq. 1) Torque = (hp x 5250)/Speed (eq. 2) As an example, a 1-hp motor operating at 1800 rpm will develop 2.92 lb-ft of torque. Know your load torque requirements Every load has distinct torque requirements that

The linear model of a D.C. motor torque/speed curve is a very good approximation. The torque/speed curves shown below are actual curves for the green maxon motor (pictured at right) used by students in 2.007. One is a plot of empirical data, and the other was plotted mechanically using a …
Sep 24, 2014 · A VFD on a standard induction motor is good at making sure the motor can supply a CONSTANT level of torque regardless of speed. But WR motors are capable of providing higher than standard Design B motor torque at some speeds, but the nameplate "HP" rating given to it is typically only the HP at full speed with a shorted rotor, which may not be the peak shaft torque being used

VFD supplied induction motor torque-speed curve in constant torque, constant power and high-speed area. In VFD supplied motor applications, it is important to note that torque-speed curves show the torque the motor can produce for each frequency, but not for how long and if motor can operate in each condition continuously
Torque = (hp x 5250)/Speed (eq. 2) As an example, a 1-hp motor operating at 1800 rpm will develop 2.92 lb-ft of torque. Know your load torque requirements Every load has distinct torque requirements that vary with the load's operation; these torques must be supplied by the motor via the VFD. You should have a clear understanding of these torques

For every motor, there is a specific Torque/Speed curve and Power curve. The graph above shows a torque/speed curve of a typical D.C. motor. Note that torque is inversely proportioal to the speed of the output shaft. In other words, there is a tradeoff between how much torque a motor delivers, and how fast the output shaft spins. Motor characteristics are frequently given as two points on this graph:
Sep 20, 2017 · “For a milling application, one of the main concerns we look at is for a VFD that can provide full motor torque even at slow speeds or lower frequencies. For the category of micro-drives, (3Hp and below), most VFDs have two modes of operation; general purpose and sensorless vector or sometimes called vector control
