This series is suitable to operate in such an indoor environment with an altitude not more than 1,000m and a coolant temperature not more than 40ºC, with less dust, and without vapour, acid, alkali or corrosive/explosive gas. The rated voltage is 6000V for this series, and we can design with 3000V and 10000Vaccording to the requirements from the customers. Its allowable voltage deviation range is +5%, rated supply frequency 50Hz and rated power factor 0.9 (lead).
The motor has a cylindrical shaft extension, whose rotation direction shall be consistent with that on the nameplate, ordinarily anticlockwise when seen from the end of collecting ring, and also, we can produce the ones with a clockwise rotation. When a coupling is used to connect the motor and a mill, the motor's shaft extension shall not bear extra radial or axial force. 50hz and rated power factor 0.9 (lead).
The series adopts a stationary controllable silicon exciter.
It is allowed to be directly started at full voltage, when such starting mode is not allowed due to the capacity of the power grid of one user, it can be started at reduced voltage, at this time, the decrease of its starting current is in direct proportion to its terminal voltage while the decrease of starting torque is in direction to the square of its terminal voltage.
Stator leads: 6 leads, respectively U1, V1, W1, U2, V2 & W2, all of which are led out by a high-voltage cabtyre cable from the terminal clamp at the bottom of the frame, and can be led out by a junction box customized according to customer requirements.
Pedestal bearing: ring-oiled or combined bearings adopted, installed between baseboards and underlaid with insulating padding plates to prevent shaft current.
Pedestal bearing: ring-oiled or combined bearings adopted, installed between baseboards and underlaid with insulating padding plates to prevent shaft current.
Frame: welded by steel plates, leading-out terminal at the bottom.
Stator: its iron core is made of piled fanning strips stamped with 0.5mm low-loss silicon steel plate, and is separated by radial duct spacer; stator windings adopt formed double-layer short-pitched coils with an insulation class of B or F (temperature rise assessed according to class B), that are helpful to prolong service life; and because winding terminals have been fixed and strapped reliably and processed with solvent-free VPI (vacuum pressure impregnation) and have gone through many times of tests for turn-to-turn impulse withstand voltage and withstand voltage to ground, the motor has excellent and reliable insulation performance, high mechanical strength and strong moisture proofing.
Rotor: its magnetic poles made of stamped steel plates which are installed at rotor field yoke together with pole coils with an insulation class of B or F. When a customer wants to adopt a pneumatic clutch, we can design a revolving shaft or a shaft with punched holes according to customer requirements.
The series is a kind of large-sized 3-phase AC synchronous motor mainly used to drive mills in mines, including grate ball mill, rod mill and coal mill. Product Name: High Voltage Ball Mill Synchronous Motor Rated voltage: 3000V, 6000V, 10000V Capacity range: 320 kW ~ 5000kW Rated frequency: 50Hz, 60HZ Cooling method: IC01 Quota: S1 Synchronous speed: 150-187.5r/min Insulation class: B Temperature rise level: B Connection: Y Protection level: IP00/IP21 Power factor: 0.9 (leading) Excitation mode: static thyristor (other excitation methods can also be made) Altitude: no more than 1000m This large-scale high-voltage synchronous motor is suitable for use in environments where the ambient air temperature does not exceed 40 ° C and there is no serious dust, the minimum ambient air temperature is -15 ° C, and there is no corrosive and explosive gas in the air (which can also be made into a damp heat or high-altitude motor). This series of ball mill synchronous motor adopts new technology, new materials, new technology, colorful and exquisite, well-made, specific small volume, light weight, high efficiency, low noise, small vibration, safe and reliable operation, convenient use and maintenance. The motor has an advanced power factor (which improves grid power factor), high efficiency, high stability and high overload capability, and has the performance that the speed does not change with load. The company has large-scale laboratory, intelligent CNC winding machine, CNC rising machine, automatic wrapping machine, VPI high pressure vacuum immersion system, large-scale dipping paint drying furnace, 60 tons test platform, large vertical car, milling machine, grinding machine, Each type of dynamic balancing machine, double-feedback test and detection system with 6MW (12MW) motor and other motor production professional equipment more than 500 sets, sound mechanical equipment processing capacity, to lay a good foundation for customers to improve good quality motor products. 1. The outer packaging of the products are all standard export-oriented wooden plywood packaging. 2, the product packaging is protected by moisture, water plastic soft packaging 3. For products with special transportation requirements (such as temperature, fragile, variability, and easy to get wet), the packaging protection measures will be strengthened, and the target mark will be printed on the package. 4. There are obvious signs and symbols on the packing box that must be paid attention to during transportation and storage (such as position, moisture, rain, shockproof, lifting position, etc.). There are many types of motor products manufactured and sold by our company. The main products are high- and low-voltage three-phase asynchronous motors. The motor structure types include squirrel-cage type and winding type. Among them, high-voltage synchronous motors mainly support air compressors and mine ball mill equipment. use. We adhere to the service tenet of "focus on products, service with heart" and provide high-quality motor products to customers.
