Hi
I was just wondering if anybody would know of an encoded brushless motor equivalent to a nema 17 3d printer sized motor. I.e. similar torque etc
Thanks
"NEMA 17" specifies the dimension of the motor mounting face plate. There are thousands of motors, with different voltage, current and other specifications, that have that size face plate.
To shop for motors, you first need to determine what power, torque, etc. the project requires, then use those specifications to find a suitable motor.
A standard Nema 17 stepper is already brushless.
If you mean a Nema stepper with a built in encoder you only have a few choices but be prepared to pay much more.
Or you could just get a regular nema 17 with a dual shaft and drop a home brew encoder on it.

A BLDC can't have similar torque to a stepper motor as stepper torque falls dramatically with speed and
DC motor torque is dependent on the current and not the speed.
So they are not comparable at all.
You need to bypass this xyproblem and tell use what you are trying to actually achieve.

Thanks for your help and sorry for my vagueness.
I've made a 3 axis camera slider (linear sliding axis and pan and tilt axis') with stepper motors, however, they are both loud and are unable to move very fast. I was looking for encoded brushless dc motors that could replace. If there are any other solutions as well that would be great.
I have also looked into different drivers such as the TMC2100 but didn't know whether this would solve the problem.
Thanks
You need servomotors or fashion your own using encoders and DC motor and a PID loop. You need to
find out the torque requirement and speed requirement as the first datapoints. That determines the
motor power, and gearing ratio.
