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...
To use an induction motor to drive a load, for example, a fan, a pump, a compressor, or a conveyer, it is important to know the load torque-speed curve and to analyze its interaction with the motor torque-speed curve. This is to ensure that the motor will start successfully and opera...
Typical induction motor torque-speed curve. The locked rotor torque is the torque developed by the motor at standstill. This torque is sometimes also referred to as the starting torque. The pull up torque is the minimum torque developed by the motor as it accelerates from standstill to 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 ...
The impact of windings switch-overs on torque-speed curves of the motor has been analysed. Analytical method which makes it possible to determine torque-speed curve of this motor very easily has been elaborated. Computer model of PM BLDC motor for Matlab/Simulink software has also been worked ...

A servo motor torque curve depicts the amount of torque the motor can produce over its range of operating speeds. There are two operating zones on the torque-speed curve: continuous and intermittent.
通过Motor-CAD软件可进行无刷永磁电机的运行性能、损耗以及热分布的计算。本教程将对该类电机电磁热互耦计算进行详细介绍。定义模型 Motor-CAD软件中有BPM电机的电磁计算模块及热计算模块。两种模块既可以单独进行仿真计算，还可以实现电磁热间的互耦分析。本教程中，首先使用电磁计算模块对样机的电磁性能进行分析。如下...
电机应该有多大的扭矩(torque)和速度(speed)。什么功率(power)和效率(efficiency),电机应该有多长(length),电机应该有什么直径(diameter)。你应该首先确定具体应用的要求,例如,电动汽车、电动船或电动飞机。 由此,得出对电驱动和电池系统的要求。从电驱动(electric drive)的要求中,可以得出对电机和逆变器(inverter)的...
