Infinite Rotation Servo vs Stepper Motor
« on: August 04, 2012, 02:30:25 AM »
What is the difference between the 2 please?

They seem to be the same... except maybe for the extra torque offered by a servo.

How would an infinite rotation servo act when added to a servo controller (say Pololu)?


Thanks!

They are very different animals. A stepper motor is a motor with a finite number of positions each revolution, while an R/C servo, whether infinite or limited rotation, is a combination of motor, gearbox and motor controller.

Steppers are drven by energizing the vindings sequentially (controller needed). The servo is controlled by a PDM signal (1..2ms pulse repeated each 20ms).

A rather fast and fairly heavy robot with quite large wheels needs what? A lot of power?
