7-7 GEAR TOOTH FORM SUITABLE FOR DETECTION
The recommended tooth form and dimensions are shown in the drawing below. If the teeth are
smaller than the below dimensions , the amplitude of the detection signal becomes so small that
detection error may result.
(1) Gear
(2) Projection
• To detect a projection (gear), provide surface A of the projection with a concentric
curve. Do not make it flat.
(3) Key groove
(4) Target for rotor speed detection
