This blog will provide you all the necessary information that you might need when you want to do some work with a RS775 DC motor.
Before starting let me tell you that we also provide all video links for 775 motor testing.
It includes motor current in Load and No load, voltage , torque, Suitable Adapter or battery and RPM also.
So as we all know that RS 775 is a very popular type motor. Its very common and powerful in DC 12-24 volt range motor.
You might ask what is that 775 means, its just a serial no to denote this motor..
Its a standard pic of 775 motor with bearing. 775 dc motor comes in bearing and non bearing both. Here we give details of a Bearing motor.
