Large high-voltage synchronous motors are ventilated by open natural ventilation or can be made into fully enclosed ducted ventilation.
High-voltage synchronous motor base: welded by steel plate, the lower part of the base is the outlet end of the motor.
The rotor of a large synchronous motor: the magnetic pole is made of steel plate, and is mounted on the rotor yoke together with the magnetic pole coil. The magnetic pole coil is B-class or F-class insulation. When the user uses the pneumatic clutch, the rotary shaft design can be designed according to user requirements or The shaft is punched (the center is long and the through hole is blocked, the shaft end is blocked, the air head is installed on the shaft head, and the other end is processed as required, and the bolt hole is connected to the rotary joint of the air clutch).
The stator core of the synchronous motor is formed by stacking segments of 0.5 mm thick low-loss silicon steel sheet, and the core segments are separated by radial ducts; the windings are formed by double-stacked short-span coils, using Class B insulation or Class F insulation, temperature rise according to Class B assessment to facilitate extended service life; winding ends are reliably fixed and tied, and vacuum pressure impregnated solventless paint process (VIP) treatment, after multiple turns in the manufacturing process Withstand voltage and ground pressure test, the motor has excellent insulation performance, good mechanical strength and strong moisture resistance.
Our company's large-scale high-voltage synchronous motor is a professional synchronous motor supplier based on years of R&D and production experience and the introduction of advanced manufacturing technology. The technical requirements of this series of motors, except those specified in the special technical conditions of the products, are in compliance with the IEC standards. The mechanical dimensions of each part of the motor are in accordance with the Chinese national standard GB1800-1804 and the ISO standard of the International Standardization Committee.
The protection level of the large synchronous motor housing has IP00, IP20, IP21, IP23 and IP44 according to GB4942.1 and IEC34-5 "Motor enclosure protection level".
This series of synchronous motor cooling methods are based on GB1993 and IEC34-6 "Motor Cooling Method" standards, including IC01, IC27, IC37, IC81W, and IC91W. The basic installation method of the motor complies with the provisions of GB997 and IEC34-7 "Motor Structure and Installation Type Code". If the user needs other protection levels, cooling methods, and installation methods, they can be negotiated separately.
The direction of rotation of the motor is clockwise from the end of the shaft. The motor allows direct starting at full pressure. The motor housing protection type is heavy straight anti-drip type, and can also be other forms. According to user requirements, the ventilation form of the motor can be ventilated or reversed (wind inlet).
Excitation mode: This series of motor excitation system uses thyristor excitation device.
The stator core is formed by laminating silicon steel sheets of 0.5 mm, and the stator core is fixed on the frame by a tensioning screw.
Stator coil: The coil is a stack winding, which is insulated by F pole and has anti-corona measures. The ends of the coils are securely fastened and treated with an integral VPI vacuum dipping finish.
Magnetic pole: a magnetic pole punch punched from a thin steel plate is laminated, and a magnetic pole core jacket is a magnetic pole coil. The entire magnetic pole is mounted on the yoke.
Magnetic pole coil: It is made of copper flat wire and is insulated by Class F insulation.
The front and rear bearings of the large synchronous motor adopt a seat type sliding bearing, and the bearing is equipped with a pressure thermometer and a transparent cover for oil filling. Check holes for easy oil filling and oil mist spillage. The slip ring assembled by the motor is fixed to the non-axial extension end of the main shaft and is coaxial with the main shaft. The jump is small and easy to overhaul. The slip ring brush holder is fixed to the seat block of the non-shaft end. Motor bearings, winding temperature measurement and heating devices can also be added according to customer requirements.
