摘要:
A pneumatic motor unit including a housing (10) with an air inlet passage (11), an exhaust air outlet passage (12) and a rotation motor (13) of a kind generating a pulsating exhaust air outlet flow, a voltage depending device (32) for communicating signals in response to the actual motor condition and/or operation parameter values, and a voltage generating means (34) connected to said voltage depending means, wherein the voltage generating means (34) comprises a piezo-electric element (35) located in the exhaust air outlet passage (12) and arranged to be activated by the pressure pulses of the pulsating exhaust air outlet flow from the motor (13).The piezo-electric element (35) is tongue shaped and rigidly secured at one end and arranged to be swung in two-way movement relative to a central rest position to thereby generate an alternating current voltage.
