    • A motor arrangement has an electronically commutated motor of an explosion-protected design with a permanent-magnetic rotor, a stator, and an electronic commutation device. At least one galvanomagnetic rotor position sensor is arranged on the stator and separated from the permanent-magnetic rotor by an air gap, wherein the at least one galvanomagnetic rotor position sensor is configured to detect a magnetic field of said permanent-magnetic rotor and emits an output signal controlling said electronic commutation device. An opto-coupler transmits the output signal of the at least one galvanomagnetic rotor position sensor to the electronic commutation device. A current supply in the form of an ac system or a three-phase system supplies current to the at least one galvanomagnetic rotor position sensor. An isolating transformer is interconnected between the at least one galvanomagnetic rotor position sensor and the current supply.
