    Simulating Howland current pump in Multisim - something amiss

    I believe I've copied the Caldwell high current bidirectional current source design but my design tops out at 4.5mA in the 10k load (R7) for any input over 4.5V I would very much welcome another pair of eyes on this or some insight into what I've done to upset Multisim.

    Find unknown current from CCVS circuit.

    - My Goal ; find Ix from given Cicuit - What I've tried ; Use KVL (at Loop1 )and KCL (at Yellow Node) to express arbitrary current with Ix * I use KCL at right above blue arrow, then got \(i_1 = I_x -4\) This is the equation what I've set up \[ 4I_x + 2(I_x -4) + 2i_2 - 2I_x = 0\...

    Motor Driver Unit Design

    Hi I am doing a third-year design project and I have been assigned to do the motor driver unit part. Based on the research I made, I founded out that the single-phase stepper motor can be driven in two ways namely VFD and Stator power supply control. I was able to come across a triac crowbar...
