Dynamometer
(optional)
A compact
dynamometer (“dyno”) may be purchased with the Zynq Intelligent Drives Kit II. The dyno provides a test
fixture to dynamically apply a load to the motor. A 3-phase MOSFET bridge, under command of an integrated digital
controller, adjusts the resistance seen at the phase leads of the load motor. Optionally, the load motor may be
connected to FMCMOTCON2 to be directly driven from Zynq. An LCD and 3 push buttons on board the dyno provide
a user interface to dynamically change load profiles and view measurement of the load motor speed and current.
More details, including schematics, bill of materials, and board files can be found at the Analog Devices wiki.
