Model No. DL MAC-CCC_EDL MAC-CCC_U
The Dl Mac-Ccc Is A Multipurpose Bench For The Speed Control Of Direct Current Motors Of Eurolab (0.3 Kw) And Unilab (1.1 Kw) Electric Machines.
The Dc Motors Are Used In A Wide Variety Of Industrial Drives, Such As Robots, Machine Tools, Oil Drilling Rigs, Mining, Automotive Systems, Etc.
Their Speed Can Be Easily Adjusted In Very Fine Increments Ranging From Standstill To Rated Speed And Even Above And Their Construction Is Made Rather Complex Than Their Ac Counterparts By The Fact That They Need A Commutator, Which Reverses The Direction Of Current And Fluxes To Produce A Net Torque.
The Dc Motor Speed Controller Is Built With A Single Phase Semi-Controlled Thyristor Bridge Suitable For The Control Of The Speed Of Independently Excited Dc Motors By Regulating The Conduction Period In Open And Closed Loop.
The Controller Consists Of Three Control Loops: Speed, Current And Armature Voltage (For This Latter It Is Necessary To Use The Isolation Amplifier).
EXPERIMENTS
The experiments that can be performed are:
– Rotor voltage regulator
– Tachometer regulation
– Meaning of gain
– Resistive load (in thyristor bridge)
– Step response of the current regulation
– Step response of the speed regulation
– The operational amplifier (and transfer function)
– Bode diagram for the current and speed regulations
