Reversible Motor Driver – Rohm

I don’t understand your statement “. It will do this at the current you are drawing. Copy your embed code and put on your site: If you had a plus and minus supply I would suggest you use a power op amp. The VR max voltage is 5V, to turn the motor, 0.

BAB 데이터시트(PDF) – Rohm

Students Click Here Join Us! When motor is at rpm, that means cemf is about Do I understand this correctly, you are telling the motor to go only forward but it goes both forward and reverse? I have try to eliminate the 10 ohm by connecting a wire but it burn out the B IC. However, in the app. You should also make sure the motor is unloaded during this learning experience. How to measure datasheeet ohm of the motor I am driving?


When the motor is running in just the forward direction, how much current does it draw?

Take that ohmmeter you used to measure the ohms of the motor and put it on the Ampere scale or milliamp scale and measure the current flowing through the resistor. It is as yanco measured previously, 12 ohms.

One thing you should note is, with the 18 volt supply you have chosen, any linear device you use will have to drop the difference between the 18 volts and your load voltage. Pin CD1 and CD2 are tied to ground with capacitors of ceramic 0.

Two logic inputs allow four out. So one would wonder what the resistance of your load is. Place as near as possible to the V pin. I am not familiar with motors this small but I would think that somewhere when you are running it the current should be below 0. I am dayasheet sure you understand that in the data above, you are suppling 3 times the rated current to the motor when you change directions. Should not that read 18 V voltage across 20 ohms?

BA6219B Datasheet

Refer to my post to Schwarz to see how the motor should be behaving. By joining you are bz6219b in to receive e-mail.


Ok, you’ve got my interest. No wonder it is hot. This will help to fill in the picture of your application. Is it possible to measure the current through the motor either while measuring the current through the resistor or under the same conditions?

Therefore Kv is probably close to Your chip is a linear device. The output is supplying 12 V to the rest of the circuit. Your RMS current in the motor, I would think would lead to decreased motor life. Or are you using logic to turn it dataheet forward and reverse?

Elcodis is a trademark of Elcodis Company Ltd. We call this ‘dead-time’. I means one of them will have 3 V, one of them zero, and vice versa.

Perhaps your motor is undersized. The motor resistance is 12 ohm when I measured. This creates watts, which then creates heat.
