Embodiment Construction
[0020] in accordance with figure 1 , the compressor has a single cylinder 1 in which a piston 2 is arranged for compressing compressed air drawn from the environment through the cylinder head 3 . The linear working movement of the piston 2 is produced by a crank drive, which essentially consists of a crankshaft 4 together with a connecting rod 5 . The crankshaft 4 is mounted rotatably relative to the compressor housing 7 via two rolling bearings 6 a and 6 b.
[0021] The compressor housing 7 consists of a first housing half 8 forming the crankcase and a second housing half 9 accommodating the electric motor 10 .
[0022] The electric motor 10 is designed as a brushless motor in this exemplary embodiment and comprises a stator 11 composed of coil windings with an iron core, which interacts with a rotor 12 equipped with permanent magnets. The rotor 12 of the electric motor 10 is screwed onto the conical end of the crankshaft 4 , which protrudes into the second housing half 9 ....
