Technical features
The innovative SIN-COS concentric Hall effect sensors, used in conjunction with a magnetic ring, provide the motor controller with absolute shaft position feedback in the form of a sinusoidal waveform.
They are the ideal solution for those who wish to minimise the radial dimensions of the motor and may or may not require a through shaft. Precise and reliable up to 8000 rpm, these sensors also offer, thanks to the integrated firmware, the possibility of setting a normalised output signal in a Vpp range and a starting phase independent of the actual zero position of the shaft (phase offset).
The setting of this last parameter is necessary for applications where it is necessary to know the initial position of the rotor, but it is not possible to adjust it mechanically once the motor has been assembled.
Mechanical configurations
The standard mechanical configuration includes 4 mounting flanges. Possibility of creating customised versions.
Applications
The SIN-COS Elen sensors with concentric mounting are applied on PM AC Brushless electric motors intended for different types of work and transport vehicles.
