I’m making a soccer ball shooter. I have two, roughly,90v motors. They each have a mc1200 control board. I’m also using the actuator to raise/lower the machine. Currently I’m using the treadmill displays to control them. The displays are quite large, so I’d like to use something smaller to control the speed And actuator. The ultimate goal would be to have the speed,actuator and small selinoid(to control ball feed) in a remote. So basically up/down speed, up down actuator, and button to release the next ball. Any help would be greatly appreciated. Thank you

as a bonus I have a link to the prototype(not welded just taped together, hence the rattling)

 

For the speed control, you just need a 20Hz PWM signal into pin 4 of HD2.
A suitable series resistor has to be used dependent on the volt output of the PWM.
There are some cheap units out there that will do it, I also have made up some small (50mm x 50mm) Picmicro based RPM controller boards for spindle control .

 

I was given the opinion to keep the display control as is currently. Everything works well. They suggested using an esp32 integrated into the control. This way everything can be conteolled. Any thoughts?

 

For remote control, modules like the NRF24L01, Bluetooth (e.g., HC-05), or WiFi (ESP32’s built-in) would work.

I know that for baseball shooters the motor speeds can be made different, to put spin on the ball. Is that a desired function??
I am not familiar with those motors, are they Brushless DC , or do they have brushes? That will affect the drive electronics.

 

Brushed DC, 2hp - 3,5HP

 

OK, the ball shooter system is not so simple! The obvious controlled functions are the vertical angle, ball speed, and then a trigger to fire ball. Individual speed control for the two motors will allow setting a spin on the ball, like baseball shooters have.
Also there might be a start and stop command for automatic repeat shots, although that might be a dumb idea. A master-stop command is a good choice for if something goes wrong, also.

One big concern will be the size of the control box, which certainly will be bigger if the whole TM boards are used.

Looking at the video it would seem you are using 2 MC2100's, one for each motor? How are you synching them?
If you want to make the control panel smaller I suggest using a micro of some kind, I have used Picmicro in the past in order to make a smaller operator control panel.

 

The motors can run at different speeds to put a spin on the ball, just like the pitching machines do. Have you noticed that sometimes a soccer ball does not bounce the way you expected to see it bounce?? That is because of the spin.
