The outer wall of the mounting sleeve 6 has a number of phase-changing pieces 1 and mica pieces 2 distributed equidistantly around the circumference. The evenly distributed phase-changing pieces 1 and mica pieces 2 realize the motor commutation function. The outer walls of the phase-changing pieces 1 and the mica pieces 2 are bound with alkali-free tape 3 and mesh non-woven tape 4. The alkali-free tape 3 and mesh non-woven tape 4 are bound and fixed on the outer circumference.
