1. Select a section of chute on the stator core, which is usually the position closest to the stator teeth.

2. Use measuring tools such as caliper or outside micrometer, put the caliper or outside micrometer into the chute, measure the width of the chute, and then record the measurement results.

3. Measure the depth of the chute with measuring tools such as depth micrometer or needle ruler, and then record the measurement results. Divide the chute depth by the chute width to get the ratio of the chute degree, which is the stator core chute degree.
