摘要： 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.

摘要： An electronically commutated external rotor motor has an external rotor having a cup-shaped housing and a radially magnetized permanent magnet connected in the cup-shaped housing. An interior stator is positioned in the cup-shaped housing. The interior stator has a laminated core having grooves. Windings are provided within the grooves. The windings have first end turns proximal to a bottom of the cup-shaped housing and second end turns positioned distal to the bottom. The first and second end turns electrically connect the windings to one another. The permanent magnet has an end face remote from the bottom of the cup-shaped housing. At least one galvano-magnetic rotor position sensor is arranged opposite the end face of the permanent magnet so as to be located within a magnetic leakage of the permanent magnet and within a magnetic leakage of the interior stator. The at least one rotor position sensor is designed to control current within at least a portion of the windings. A magnetic leakage flux concentrator is arranged at the interior stator at the second end turns at a side of the second end turns facing away from the laminated core and positioned at least within an angular area of the interior stator in which the at least one rotor position sensor is located.
