Good morning folks,
my problem in short: I'm looking for the right full-bridge IC (single or double). I would like to be able to both power it and control it with 24V and the output voltage should also be +-24V. The load is only around 40mA. Does anyone have a good suggestion?
Detailed explanation: At work I'm working on a self-made model of an electric motor. Right now it's built with a rotor with permanent magnets, which is turned by 6 individual coils, which I removed from old relais. The coils are controlled with 24V by a PLC.
To improve the system I would like to be able to change the polarity of the coils while running the motor. With the normal digital outputs of the PLC I'm limited to only one polarity and analogue outputs provide only +-10V. After a day of research and puzzling about MOSFETs and full-bridges I let go of the idea of building my own bridges, because I'm lacking the know-how at this point. That's why I'm looking for fitting full-bridge ICs to individually control the coils. The requirements would be that I can both power and control the chip with 24V via the PLC and that the output voltage is also 24V, which is the nominal value for the coils.
Greetings
Wolfgang
