Abstract: An electromechanical watch including an electromechanical motor (4) mechanically coupled to an analogue display (AD) and formed by two coils (B1, B2) through which the magnetic circuit (10) of the stator passes. A first of the two coils is connected to a voltage detection circuit (CD1, CD2) arranged to be able to detect any voltage induced in this first coil during intervals of time occurring, in a stepping functioning mode of the motor, between drive pulses to detect whether an unwanted step is made by the rotor (18) during these intervals of time. The electromechanical watch includes at least one switch (T1, T2, T3) that is controlled by an electronic control circuit (CEC) to short-circuit the second coil during each of said intervals of time, in order to passively hold the rotor in the idle position in which it is situated momentarily between the drive pulses.

Abstract: A hammer drill (100) comprises an electric motor (110), a piston (127) as a driving member and a controller (199) which controls and drives the electric motor (110). The piston (127) is reciprocated by rotation of the electric motor (110) and thereby a hammer bit (119) is driven in its longitudinal direction. The hammer bit (119) is moved forward in response to a forward movement stroke of the piston (127) and thereby a hammering operation is performed by the hammer bit (119). The controller (199) sets a duty ratio of a driving pulse signal which drives the electric motor (110) in the forward movement stroke of the piston (127) to be larger in order to prevent a reduction of a rotation speed of the electric motor (110) due to a load applied on the electric motor (110) during the forward movement stroke of the piston (127).

Abstract: A current sensing circuit may include a shunt resistance through which current to be sensed travels. A first and a second differential amplifier may each provide an amplified output of the voltage across the shunt resistance. A switching system may deliver a current sensing signal output based on the amplified output of the first differential amplifier when the common mode voltage across the shunt resistance is low and based on the amplified output of the second differential amplifier when the common mode voltage across the shunt resistance is high. The first differential amplifier may provide its lowest output DC offset voltage when the common mode voltage is low, while the second differential amplifier may provide its lowest output DC offset voltage when the common mode voltage is high. The first and second differential amplifiers may both have a low common mode voltage rejection ratio, such as a ratio of less than 40 db at the switching frequency of switches that control the current that is sensed.
