Ok, putting the speed controller immediately after the power supply seems to have resolved it, now have equal speed in both directions!
Many thanks for all the help!
Dave.
Hi,
The speed controller is: http://www.quasarelectronics.com/cr0006-dc-motor-controller-module-18-24v-6a.htm
I reversed the wires on the output side of the controller - so hopefully it isnt fried!
Will try wiring it without speed controller at all & see the effect!
Sorry, should have been more specific, only the power supply & motor are cannibalised, all the relays, wiring, and the speed controller are new parts.
Will try swapping the wires & let you know!
Thanks,
Dave.
Its original application had it driving a much larger load through the same gearing in both directions,(I've cannibalised an old machine to make a new one!)
so guess from that the motor should work equally well in both directions?
Not sure how to tell what direction it might be designed for?
Its a brushed motor - see attached for data sheet.
Many thanks,

Hi,
Apologies, have had a go at drawing one here, hope it conveys what I've got!
Essentially two DPDT relays one changes the motor direction, the other switches everything on & off.
S1 & S2 are limit switches (have tested & they work)
The two SPDT relays are part of a PC controlled board...
Hi,
Apologies if this is a dense question - my background is mechanical, not electrical!
I've got a 24Vdc motor connected to a 24Vdc, 6A, power supply.
The circuit runs through 2 relays, one switches the circuit on & off, the other reverses the motor direction.
I also have a motor speed...
