The torque-speed curve is similar for all centrifugal pumps due to simple math: the pump torque varies as the square of its speed. However, when the pump is at rest—0% full load speed—the full load torque is never also 0%. Starting a rotating pump requires the motor to overcome the...
在电磁热互耦设置中,选择最后一项”Iterate to converged solution”。 注意:为了提高求解书的,移除"Back EMF", "Cogging Torque", "Torque Speed Curve" 以及“Self and Mutual inductance” 的求解项目,只保留"Torque"。 点击图标'Solve E-Magnetic model' 进行求解,此时将弹出如下对话框: 点击OK按钮进行电磁热...

A number of techniques have been used to quantitatively probe the behaviour of individual BFMs by determining the motor’s torque-speed curve, which is analogous to force-velocity curves used to characterize linear motors8. In particular, torque-speed curves of BFMs have been profiled using the ...
Electric Motor Driving Speed Reduction Calculator Where:T = Required Torque, lb-ft = Reflected inertia, lb-ft2 = Load inertia, lb-ft2 = Reduction ratio = Change of speed, rpm t = Time to accelerate the load, seconds = Change speed of shaft, rpm...
The servo motor torque curve shows two operating zones — continuous and intermittent. The continuous operating zone encompasses the combinations of torque and speed that the motor can produce indefinitely. When evaluating whether an application lies within the continuous duty zone, the motor’s root ...
This paper proposes a speed and current proportional-integral-resonant (PIR) control strategy to realize smooth speed control of the low-speed high-torque permanent-magnet synchronous motor (PMSM) drive system by minimizing the periodic torque ripples. Some nonideal factors causing periodic torque rippl...
Hello, When I plot the torque-speed characteristics for a certain motor that I am designing I am getting the curve below. I don't know why I am getting that dip in the middle of the plot. I tried changing the increment and I still got that dip at a diffe
