Hi Michael,
Many thanks.
OK, another study reveals that with my setup I was usiing 22 Ohm resistors at 24v supply.....WRONG.... should have been 24V supply, less 1.7 Motor volts = 22.3, divide that by the phase current of 4.7 amp makes the resistor value 4.7 Ohms.
I used a 12v supply with 2.2 Ohm resistors and things get a lot more interesting. Much more torque, I will look out for some 4.7 ohm resistors next week.
Thanks for your input
