Embodiment Construction
[0018]FIG. 1 illustrates an inclined-axis motor having a first housing variant 6a, in which the rotation speed sensor 1a according to the invention is installed. The housing 6a is connected to the gear mechanism 7 via a flange, only housing parts of said gear mechanism 7 being indicated here. The drive mechanism of the inclined-axis motor comprises in a known manner a cylinder block 8 and a pivoting mechanism 9, which are arranged in the region of the end housing 10.
[0019] The rotation speed is tapped off from the shaft 5, which is mounted in a fixed position in the housing 6a and on which an annular, magnetic pulse generator 4 is fixed, said pulse generator 4 producing corresponding pulses in the sensor element 3, a Hall probe, on rotation of the shaft 5. The Hall probe 3 is arranged on a printed circuit board 13, which extends along a first limb 14 of the L-shaped rotation speed sensor 1a. The limb 14 requires very little physical space. It can be matched optimally to the free sp...
