Abstract: PROBLEM TO BE SOLVED: To suppress a phase current generated in winding of a stator over a full speed range of motor when driving a stepper motor in a voltage mode. SOLUTION: A method of driving a stepper motor in feed-forward voltage mode includes (A) a step of setting the amplitude of a sinusoidal phase voltage of the stepper motor to a predetermined value to rotate the stepper motor at a desired speed. The predetermined value is the sum of a back-electromotive force (BEMF) estimated via a function of the desired speed and a product of a desired amplitude of a phase current (Iphase) and an estimated absolute value of the impedance of the stepper motor.

Abstract: PROBLEM TO BE SOLVED: To enable a reduction in the influence of the disturbance components, superimposed on signal components caused by rotation of a gyroscope itself. SOLUTION: A micro-electro-mechanical gyroscope includes a first mass 107, which is able to oscillate along a first axis with respect to a fixed body, and an inertial sensor 6, having a second mass 108, constrained to the first mass so as to oscillate along a second axis, in response to a rotation of the gyroscope. A driving device 103, coupled to the first mass, forms a control loop for maintaining the first mass in oscillation at a resonance frequency. A reading device, which detects displacements of the second mass along the second axis, includes a charge amplifier for converting charge packets (Q RS ) supplied by the inertial sensor into a charge-integration signal, and a low-pass filter. A calibration stage enables modification of the voltage (V B ) between the second mass and the fixed body so as to minimize the component, at a frequency that is twice the resonance frequency in the charge-integration signal.

Abstract: PROBLEM TO BE SOLVED: To provide an integrated microelectromechanical mechanism, having high sensing efficiency and high design possibilities. SOLUTION: A first sensor mass 16a is connected to a drive mass 3 via an elastic support member 20 so as to make a first sensing motion, in the presence of a first external stress. The drive mass 3 is attached to an anchor 7, disposed along a rotation axis, and makes a rotary motion on the rotation axis z. Installed in the drive mass is a through hole 9a, in which the first sensor mass 16a is disposed. The elastic support member and the anchor cause the first sensor mass 16a to be fixed to the drive mass 3 when a rotational motion is made, and cause the sensor mass 16a to be separated from the drive mass, when a sensing motion is made. A second sensor mass 25a is connected to the drive mass so as to make a second sensing motion in the presence of a second external stress. The first sensing motion is a rotational motion, centered about an in-plane axis, and the second sensing motion is a linear motion along the direction of the in-plane axis.
