Abstract
An inductive pulse generator for converting a rotary movement into a frequency proportional therewith. The pulse generator includes a measuring wheel (1) provided with poles (3) of magnetic material evenly distributed over the circumference of the measuring wheel. The pulse generator further includes a stator (4) provided with a magnetic core (6) with plate-shaped pole shoes (10) in a coil carrier (8) out of which end portions (12) of the pole shoes (10) project. The end portions (12) face the measuring wheel (1). A coil (7) surrounds the magnet core (6), at which coil (7) a pulsating voltage can be picked off with a frequency proportional to the number of revolutions of the measuring wheel (1), outside the area of the pole shoe (10) end portions (12) facing the measuring wheel (1). The thickness of the pole shoes (10) is increased by additional magnetic material (11) so as to increase the pulsating voltage which can be picked off at the coil (7).
