• A set of two DC motors

• Motors with the High technology without ferrious rotor which assures low friction, very low starting voltage, eliminates loses in iron, assures high efficiency and good temperature conditions

• Very precise coaxial connection by a flexible Oldham coupling assures perfect connection of both motors

• Motor M1 is connected with an optical rotation sensor OPTO. The output is connected to the frequency/voltage converter (conversion of the digital information about the revolution rate to an analog voltage value).

• Motor M2 is connected with a linear tachodynamo TACHO with a very low moment of inertia.

• The tachodynamo voltage is measured by following methods:

  • output AMP3 – tachodynamo voltage

  • output OUT1 – tachodynamo voltage with variable gain (enables normalization of responses)

  • output OUT2 – tachodynamo voltage with variable gain and filtration

• Both motors are driven by precise power operational amplifiers AMP1 and AMP2 which are protected against overload

• Independent driving of the motor M2 enables to load the motor M1 according to exercise demands

• Block (FUNCTION) indicates the revolution rates in two modes – r/min or r/sec. LED diodes indicate the rotation direction

• Display in the block FUNCTION indicates also error states of the motor-generator set (motor overload, too high rotation speed, unproper power supply – see tab. Error diagnostics)

• The set is arranged in such a way, that besides a broad use in regulation techniques it can be used in the field of measurement of low power DC motors
