i am working on project for which i need to drive a pair of 5-wire Maxon EC 32 flat motors (http://test.maxonmotor.com/docsx/Download/Product/Pdf/EC_32_flat_353400_Operating-Instruction_en.pdf
), using a high voltage capable MotoMama V2.0 shield and an arduino uno.
The motor runs on 10..24V, i feed 20V into the MotoMama from an external source. Now, according to the MotoMama Spec whatever is fed into Vin should be available at the Motor outputs, however using the "analogWrite()" command i get not more than 4.8 V on the outputs.
Sadly, the motor will not run with less than 9V, and if i use its control input (feeding power to the motor directly, and using the MotoMama output to drive the speed control wire, which is prepared to receive between 0.33 and 10 V), then i won't be able to get to more than 50% speed.
am i missing something? i should say here that this is my first arduino project...
any help is greatly appreciated, also any suggestions on how i could alter the setup to get an easier and better result.
