What is electronic gear ratio in servo?
Electronic gear ratio is used to enlarge or reduce the pulse frequency obtained from a high-level controller. The numerator of a gear ratio is motor encoder pulse number per revolution; the denominator is the required pulse number, through which high-level controller represents one motor revolution.
How do I know what size servo motor I have?
Divide the motor speed by the required speed and round down to get a starting gear ratio. Then divide the required torque by the gear ratio to find the new required torque. This will narrow the choices down to just a couple of motors. Next, find a motor with an acceptable inertia ratio.
What is electronic gearing?
Electronic gearing provides a position command to a drive that depends on the motion of another device. That device is typically an encoder (or its equivalent) connected to a motor. However, it can also be a hand-driven encoder used to accept input from an operator or an output from a stepper motor controller.
How can I get a servo motor with high torque?
A possible remedy to get a servo motor with high torque is to add a gearhead—an arrangement of gears ensuring proportional speed-to-torque conversion. The gear ratio is the measure to which the device amplifies rotational force, while decreasing revolution rates.
How to optimize the performance of a servo?
The key to optimizing the performance of a servo system is to find the right combination of components (motor, servo amplifier, mechanical drive mechanism, feedback) and operating parameters (inertia ratio, gains and tuning values, move profile) that provides the desired performance with the highest possible efficiency.
Why is the inertia ratio of a servo important?
The load-to-motor inertia ratio is a critical parameter in servo motor sizing and performance. As we discussed in a previous article, one of the most significant effects of using a gearbox in a servo system is its ability to help optimize the inertia ratio.
How does electronic gearing for servo motors work?
And each follower can be driven at a different ratio relative to the master. It’s even possible to connect electronically geared servos in a chain configuration, where one motor acts as a master to one axis and is a slave to another axis. When electronic gearing is used, the tuning of the follower motor has increased importance.
