Wound motor with safe and stable operation

Abstract

The invention discloses a wound motor with safe and stable operation, which solves the problems of large vibration, inferior binding strength of leads at a wound rotor terminal, complex manufacturing process of rotor and slip ring lead wire, difficult wire releasing and the like. The wound motor comprises a pedestal, a rotating shaft assembled on the pedestal via an end cover and a bearing seat, a rotor fixed above the rotating shaft and a rotor lead-out device; the wound motor is technically characterized in that: a pedestal body, an end plate, a rib plate and a peripherally coated covering plate form a vibration reduction pedestal in a frame-type overall structure through rectangular reinforcing ribs and angle steel reinforcing ribs with axial full length, the side of the end cover bodyis provided with a reinforcing type end cover of the reinforcing rib, the latitude-free periphery of the coil end part of the rotor is provided with a protective ring fixing device, and a petal lead and the rotor lead-out device of a conductive rod are adopted. The wound motor is reasonable in structural design and simple in manufacturing process, obviously reduces mechanical vibration, enhances vibration reduction effect, guarantees safe and reliable operation of motor and beautifies entire appearance.

Description

technical field [0001] The invention relates to a novel winding motor, in particular to a winding motor suitable for safe and stable operation at high rotational speed (1500-2250r / min). Background technique [0002] In recent years, as the state has increased investment in infrastructure construction, related industries, especially the cement industry, have grown faster and faster. Wound motors are the ideal power for cement machinery because of their good starting performance. The country's development of new energy has led to the rapid development of the wind power industry. Therefore, the demand for wound-type doubly-fed generators has also increased significantly. As the power of the motor continues to increase, the vibration of the wound motor and the lead wire of the rotor become the key issues for the safe operation of the motor, and its reliability is the main performance index of the normal operation of the motor. There are some disadvantages in the existing woun...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a safe and stable running wound motor, which solves the problem of large vibration of the existing high-speed wound motor, poor binding strength of the lead wires around the end of the rotor, complicated manufacturing process of the rotor and the slip ring lead wire, and the problem of wire outlet. Compared with existing similar products, it has a reasonable structural design and simple manufacturing process, which significantly reduces mechanical vibration and improves the vibration damping effect. It not only ensures the safe and reliable operation of the motor, but also adds to the overall appearance.
