subject: Quick Information On Motor Controls [print this page] D u knw hw motor controls work? Th wll control th movement f motor. It designed fr larger motors frm overload r frm hvng n vr current condition. Th dn wth protective overload relay r temperature sensing relay. Fuses nd circuit breakers r l uful fr vr current protection. Thr r automatic motor controllers tht m wth limit switches t protect th driven machinery. Thr r mn dffrnt types. Read th article t understand more.These controls r device tht controls th position, velocity, nd torque f mechanical drive. It designed fr motion controls f electrical motors. It h automatic nd manual transmissions fr starting nd stopping th motor, choosing nd regulating th speed.It l for choosing thr frwrd r reverse rotation, protect gnt overloads nd faults, as well as regulate th torque. Eh electric motor equipped wth a controller whh h varying functions nd features.They n l hl.Crtn complex controllers r ud t control th speed nd torque f connected motors. In closed loop control system, controller produces precise positioning f t motor n numerically-governed lathe.Th controller accurately positions th cutting tool based n th pre-programmed profile. Likewise, t compensates fr dffrnt load conditions nd disturbing forces t hl k th tool's position.These r based n wht th con do. Thr r manual, automatic nd remote motor control. Depending n th manufacturer, these m nl hv start nd stop button. But thr r mn controllers tht control motor wth mn features.An electric motor control n b classified rdng t th type f motor t b driven r controlled. Th r servo motion control, step motors, alternating current r AC, direct current r DC-brush nd brushless DC r permanent magnet. Servo generic term fr n automatic control system. In practical applications, t mechanism tht u n set nd forget. It adjusts tlf durng continuous operation thrugh feedback. Servo motion controllers r part f closed loop control system fr electric motors. Th motors ud n servo control r nrmll DC. Th servo motor controls u sensor t detect motor position nd speed. A stepper motion controller viewed n electric motor wthut th commutations. Th r composed f permanent magnets n rotating shaft called rotor. Th electromagnets n th stationary area r called stator, whh surround th motor. All commutations mut b handled b th stepper motion controller, whh m n tw classifications. Th r permanent magnet nd variable reluctance. Th permanent magnet motors hv th inclination t cog whn u twist th rotor. Th variable reluctance motor spins freely.
AC motors r affordable t build nd operate. Th r l reliable bu th run frm standard line power. Th magnetic fields f th motor control r generated ung coils n th stator nd rotor. Th field movement hn naturally n th stator bu f th alternating nature f input power. DC motor controls convert electrical power nt mechanical. Permanent magnet DC converts electrical energy nt mechanical energy thrugh th interaction f tw magnetic fields--one produced b permanent magnet assembly, whl th thr produced b n electrical current flowing.
