Pitch motor
Pitch motor is applied to the pitch system of wind power generator, jointly used with the pitch planetary gear reducer.
In order to meet diverse customer demands, our Company mainly develops two series of
motor products inclusive of MSVF (ac asynchronous frequency conversion) and LG (ac permanent magnet servo).
The two series of motor have characteristics as follows:
• Operation in an environment temperature from -40℃ to +55℃, altitude less than 3,000m and relative humidity of 100%
• Capacity to operate in the air containing corrosive salt spray and fine sand
• The motor is equipped with original imported brake, fan and encoder
• The power may vary from 3KW to 11.78KW, which can be designed according to the demands of customers
• Capacity to adapt to voltage fluctuation of ±10% and frequency fluctuation of ±5%
• Working form: S1 duty
• H level of insulation
• IP55 (AC asynchronous frequency conversion) and
IP65 (AC permanent magnet servo)
• Motor’s type of cooling: IC416 (AC asynchronous frequency conversion)
and IC416 (AC asynchronous frequency conversion))
• Wide speed adjustment range, smooth torque under low speed,
no crawling and shaking
• The motor may be equipped with heating belt and heat protection
elements
• Advantages of high efficiency, low temperature rising, low noise,
long design service time and safe and reliable
• Certified by the UL and CE, qualified to export to North America and Europe
• Special designs are allowed according to the special using demands of
customers inclusive of sea, highland or high temperature
Yaw motor
Brake motor for yaw is applied to the yaw system of wind power generator, jointly used with yaw planetary gear reducer.
The series of motor has the characteristics as follows:
• Operation in an environment temperature of -40℃ - +55℃
(according to the customer demands, which can be -40℃ to - 80℃), and relative humidity of 100%
• Capacity to operate in the air containing corrosive salt spray and fine sand
• The motor is equipped with power-off brake
• The power may vary from 1.5KW to 11KW, which can be designed
according to the demands of customers
• Working form: S1duty
• Capacity to adapt to voltage fluctuation of ±10% and frequency fluctuation of ±5%
• F or H level of insulation; IP55 or IP56 level of protection, cooling type of IC411
• The motor may be equipped with heating belt and heat protection elements
• Advantages of high efficiency, low temperature rising,
low noise, long design service time and safe and reliable
• All products are certified by the CE and some of them are certified by UL,
qualified to export to North America and Europe
• Special designs are allowed according to the special using demands
of customers inclusive of sea, highland or high temperature
Special motor for hydraulic, lubrication and cooling systems
Special motor for hydraulic, lubrication and cooling systems are suitable for the hydraulic pitch system of wind generator, lubrication cooling system of gear box, cooling system of generator and control box, jointly used with hydraulic pump, oil pump, fan and water pump equipment as the wind turbine auxiliary service system.
The series of motor has characteristics as follows:
