Do not forget to setup the standard low frequency and remove the power offset!
Do you have any print screen for this setup? Yesterday and today I spent a few hours reading and re-reading the topic to find this option.
I'm communicating through google translator, and some terms can sometimes be translated wrongly.
I found some H-bridges with free shipping in goodluckbuy, which of the options below to advise your project arduino x-pid firmware?
If the second option is best for the best, I know that I will need to supply 24v and 24v engines.
Thanks for the help.
Option 1:Single 30A H Bridge Motor Driver Module for Arduino PID Intelligent Car
Descriptions:
- Designed for Arduino intelligent car, the whole bridge DC brush motor drive, is hollow cup motor is very good, PID program source send by email.
- This drive brake quickly, and easy to operation. The evaluation que its customers better than the MC33886 etc..
- The driver uses the whole bridge chip + drive extremely low impedance MOSFET.make the MOSFET switching losses to lowest. Improve power utilization rate.
- MOSFET drive hardware chip with brake function and power feedback function.
- The current shock resistance MOSFET type, resistance is 0.005 ohm, can quickly make open channel MOSFET, Improve the speed of the engine curvature, also canrapid in electrical braking. This can make of car can quickly start Also can
quickly kill car.
- Drive can work at 0% -98% of the PWM duty cycle, because the drive is NMOS circuit, NMOS circuit features is not to 100% PWM, PWM When 100% of control circuit, long time carries out the operation can lead to drive damage
Performance parameters:
- Rated voltage: 3 V-15 V
- R1 short circuit, VCC and B + short circuit. VDC output voltage and the input voltage drive.
- R1 open circuit, VCC and B + disconnect. VCC input voltage 3-12 V.
- Rated current: 30 A
- Peak Current: 70 A
- Switching frequency: 200 kHz to 1 K
- Dimensions: 5.0 cm (long) * 5.0 cm (wide) * 3.1 cm (high)
Pin Defination:
- V + Power + Input
- Power Input GND -
- EN Driver Enable, enable high, low off
- RPWM Forward PWM input, active high
- Reverse LPWM PWM input, active high
- CT Current output signal, analog signal
- VT Voltage output signal, analog signal
Package include:
- 1x Driver module
