電樞電 感的作用使晶閘管保持到 C點飛輪二極管使電樞電壓反向之前導通。 直流電機裝置的一個特征就是需要供電的負載時電阻、電導的混合,并且在圖 1中反電動勢二極管 D確保當晶閘管陽極電勢低于前面敘述的電樞連接方式的上限時,晶閘管電流應換向為零。 整流器 BR1 給并聯(lián)勵磁繞組提供一個穩(wěn)定電壓,產(chǎn)生穩(wěn)定的磁通。后者是不可能的,因此只可通過電樞電壓的變化來降低轉(zhuǎn)速。 任何電機都可以通過突然反接電源以提供反向的旋轉(zhuǎn)方向(反接制 動)來停機。 渦流制動可用于任何機器,只要在軸上安裝一個銅條 或鋁盤并在磁場中旋轉(zhuǎn)它即可。 ( 2) 渦流制動。即使負載轉(zhuǎn)矩為零,電機也必須提供足夠的轉(zhuǎn)矩來克服軸承的粘滯摩擦影響。m T,Stoica P(1989)System Hall,Cambridge,UK JH(1999)Neural adaptive tracking control of a DC Sci 118:1–13 SE(1999)Nonlinear control of mechatronic systems with permanentmag DC 9:539–552 Y,Kemp PD(2020)Modeling and control of the motion of a rolling disk:e?ect of the motor dynamics on the dynamical Meth Appl Mech Eng 188:613–624 VC(2020)Steadystate and dynamic performance analysis of PV supplied DC motors fed from intermediate power Energy Mater Solar Cells 61:365–381 JO,Jeon GJ(2020)A parallel neurocontroller for DC motors containing nonlinear 30:233–248 M,Gutman P(2020)Controlling mechanical systems with backlash—a 38:1633–1649 RH,Tung PC(2020)Studies of stickslip friction,presliding displacement,and Dyn Syst 124:111–117 K(1990)Modern control Hall,Englewood Cli?s,NJ E,Li W(1991)Applied nonlinear Hall,Englewood Cli?s,NJ PL(1993)Nonlinear process control:applications of generic model ,Berlin Heidelberg New York 直流電動機調(diào)速控制 摘要 調(diào)節(jié)系統(tǒng)的特征在于能保持輸出功率的穩(wěn)定。Speed Control of DC Motor Abstract Conditioning system is characterized in that output power to maintain stability. Different speed control system can use a different brake system, high starting and braking torque, quick response and quick adjustment range of degree requirements of DC drive system, the use of the electric braking mode. Depends on the speed control of DC motor armature voltage and flux. To zero speed, or U = 0 or Φ = ∞. The latter is impossible, it only changes through the armature voltage to reduce speed. To speed to a higher value can increase or decrease the U Φ. Keyword DC Speed Feedback Brake Regulator Systems A regulator system is one which normally provides output power in its steadystate operation. For example, a motor speed regulator maintains the motor speed at a constant value despite variations in load torque. Even if the load torque is removed, the motor must provide sufficient torque to overe the viscous friction effect of the bearings. Other forms of regulator also provide output power。不同的速度控制系統(tǒng)可以使用不同的制動系統(tǒng),在有 高起、制動轉(zhuǎn)矩,快速響應和快速度調(diào)節(jié)范圍 要求的直流調(diào)速系統(tǒng)中,采用的是
