24V Geared DC motors

[ngong123]

Hello I am trying to build a 4 by 4 vehicle using 4 DC motors Part number MPP36-WR-022V24-200-X Gear ratio 21:67:1 2 on each side [Motor] [Electro.PNG] See attached setup. After driving for few motors the power module heats up

Is there adequate ventilation where the power module is located?

No Ventilator but The power module has heat sink

Perhaps with the gear ratio and whatever size wheels you have on it you are overloading something?
