Looking for any insight on a formula that can be used to calculate the load using a magnetometer sensor for synchronous motor
yes, it can measure the directionanorlunda said:Where is your magnetometer mounted?
Can it measure direction?
Hi @anorlunda, I just want to check if I have a synchronous servo motor is this will make any differenceanorlunda said:Synchronous motor load is proportional to the angle between the rotor poles and the rotating magnetic field in the stator. Angle can also be expressed as phase difference.
If you had a compass needle mounted on the outer perimeter of the rotor by at the pole, out would point in the direction of the rotor angle. So it it's the direction of that magnetic field, not the magnitude.
Because I want to use a magnetic field sensor to get the load, I'm unable to determine the voltage or current in this case.DaveE said:But why not measure voltage and current to estimate load. Those are much easier to deal with IMO.

A magnetometer measures the strength and direction of magnetic fields. In a synchronous motor, the rotor is magnetized and the stator produces a magnetic field. By measuring the changes in the magnetic field, the magnetometer can calculate the load on the motor.
Using a magnetometer allows for accurate and real-time measurement of the load on a synchronous motor. This information can be used to optimize motor performance and prevent overloading, which can lead to damage and downtime.
While magnetometers are effective for measuring load on synchronous motors, they may not be suitable for all types of motors. Additionally, external magnetic fields or interference can affect the accuracy of the measurements.
The frequency of load calculation will depend on the specific motor and its usage. In general, it is recommended to calculate load at regular intervals, such as daily or weekly, to ensure optimal motor performance.
While magnetometers are commonly used for load calculation on synchronous motors, they can also be used for other types of motors that have a magnetic field, such as induction motors. However, the specific method of calculation may vary depending on the motor type.
