Hi

Golf trolley motor controllers.

Anyone know where to go to find the circuits for the common makes or typical
circuits?

Cheers

Ted

I have a reverse engineered diagram for a Walker Mark III golf buggy
by Parmaker Products P/L. All it consists of is a CA3524 PWM
controller driving a DC motor unidirectionally via two
parallel-connected MOSFETs. I can scan it if you are interested.

Any chance that you have a regenerative braking circuit for any
electric-powered vehicle? I would like to look at something known
to work; I will need to make a switch-mode regenerative controller
this spring to provide braking and battery recharging by a step-up
conversion from the motor back-emf (about 30V at high rpm up to
about 40V for charging).

Make sure you engineer it so that the wiper of the pot breaks contact easily
, and control goes to maximum rather than minimum, in that fault
circumstance.
Causes much hilarity on the golf course.
