A total pitch deviation measurement device that determines a total pitch deviation of an annular product having at least a magnetic ring. The device providing a frame; a pallet conveyor fixed to the frame and designed to support the rotor positioning bearing unit; a spindle unit mounted in translation compared to the frame along a vertical axis, the spindle unit including a spindle shaft, a motor driving the spindle shaft, and an encoder connected to the spindle shaft; the spindle shaft having a free lower end having a tapered shape that fits into a bore of the annular product; a sensor fixed to the frame that measures a magnetic field signal at a position of the magnetic ring and transmits the signal measured to an control unit that determines the total pitch deviation of the annular product. Also, a method for carrying out the function of the intended device.
