Motor rotor for preventing rotor winding from being thrown out

The invention relates to a direct-current motor and a winding type alternating-current motor rotor, in particular to a motor rotor for preventing a rotor winding from being thrown out, which is used for solving the problem of easiness in throwing away rotor windings during high-speed rotation of the rotor due to breakage of weftless tapes. The motor rotor for preventing the rotor windings from being thrown out comprises rotor windings wound on the rotor, wherein weftless tapes are tied at the two ends of the rotor windings; glass tape layers are formed between the end parts of the rotor windings and the weftless tapes, and fill the gaps among the rotor windings; the welftless tapes are fully contacted with the glass tape layers; the contracting degrees of the weftless tapes are the same during glue removal; and the surfaces of the weftless tapes are smooth and flat without any crack, so that the reliability of the welftless tapes is improved greatly, and a remarkable effect is achieved. The same motor rotor without the glass tape layer has the defects of a large quantity of cracks on the weftless tapes. The motor rotor is detached, the glass tape layers and the weftless tapes are formed in sequence, and drying and cooling are performed, so that the surfaces of the weftless tapes are smooth and flat without any crack, the reliability of the welftless tapes is improved greatly, and a very remarkable effect is achieved.
