Accordingly, a torque by the conduction of the coils G, H, R, S becomes only in a zone of the end of the curve 2, and the torque in the zone of the curve 2a is removed. Accordingly, the width of the rise and fall of the exciting current curves is reduced, a high speed is ...
design, smooth operation, small size, light weight, high efficiency, high specific power, the present invention is to set more of a plurality of hydraulic motors of different inputs in a case, when the motor has a different input or output, you can output more different speed and torque.闻...
In a sound emitter including an emitting piston powered by a three phase asynchronous electric motor, the torque curve of the motor may be adjusted to suit any temperature, causing variations in the emitted resonance frequency by using a motor having its maximum torque at less than half the max...
torque is established by using the Simulink simulation platform in MATLAB and combining the designed PID controller and fuzzy PID controller.And finished by aiming at each sub module in the simulation model and based on the coal mine disconnector breaking test process curve.The results show that ...
Step II: Inspecting Motor Speed-Torque Curve After all the parameters are entered in the Parameter Panel, click on the buttonSpeed-Torque Curveto display the motor torque and power over the entire speed range as shown below. These are the maximum capabilities that the motor drive system can de...
The comparison diagram of the three control methods: (a) torque; (b) rotor speed; (c) offset in x direction; (d) offset in y direction. Full size image Figure 8a show that the torque curve of two sliding mode controls are more smooth than the torque curve of the PI control. Moreove...
power losses and allowed torque of the motor were analyzed at two cases of normal and fault-tolerance operation modes.From the experimental mechanical characteristics curve,it can be obtained that the no load speeds of two operation modes are same under the same voltage,but the speed drop in ...
motor torque in order to achieve a smooth torque curve during the power-on upshift procedure.It was found in the results from the simulations that the controller is effective in reducing the torque fluctuations during the power-on upshift procedure both for a low and a high load signal applied...
