- Relays: Two 10A /24VDC relays were used as 4 switches for direction control.
- ULN2003A IC: It is a Darlington pair IC. The current required to drive the coils of the relays was fulfilled by this Darlington pair IC.
- MOSFET (IRF460N): This power MOSFET is capable of handling a large quantity of continuous currents and also its RDS(ON) is few milliohms, hence selected. Heat sink was also provided for proper heat dissipation.
- Diodes: These are 2 freewheeling diodes used whenever freewheeling was required by the motor.
Printed Circuit Board:
Complete design of this motor driver can be found in th repository links above. Here is the schematic of the PCB.
Here are some of the initial prototypes that I tried:
