Envelope Worm Gear VE7 24vdc Motor Horizontal Slewing Drive For Solar Tracking System
Envelope Worm Gear VE7 24vdc Motor Horizontal Slewing Drive For Solar Tracking System
Worm Gear VE7 Slew Drive Description
The slewing drive applied solar tracking system keep the best angle of sunlight at all times. Compared with fixed power stations, flat single-axis tracking can increase annual power generation by 10~30% (depending on latitude changes); inclined single-axis can increase by more than 30%; dual-axis tracking can increase by about 40~50%.

Features
1 Using blind hole design and skeleton oil seal sealing structure, the sealing performance is reliable, the seal can avoid direct sunlight, effectively prevent dust and water, and the protection level can reach IP65. It is suitable for outdoor use and can be output with single or double flanges.
2 Double enveloping hourglass worm, multi-tooth contact, transmits larger torque, can bear larger axial force, radial force and tilting moment
3 The product design adopts the common size at home and abroad, which is convenient for later replacement
4 Double raceway support structure, strong rigidity, can withstand large load radial force and overturning moment, especially suitable for independently driven dual-axis photovoltaic, concentrating bracket pitching azimuth and other working conditions
5 Double-sided coaxial output flange, symmetrical structure, high assembly fault tolerance, small axial size, space saving, hollow output shaft structure, convenient for wiring and structural layout
6 Imported double-lip skeleton seal ring to prevent on-site pollution
Application
Used for the rotation of the pitch position of photovoltaic power generation systems such as flat single axis, trough power generation, concentrated power generation, etc. The flat single-axis tracking system is a form of tracking bracket arranged in north-south and east-west tracking. According to the astronomical algorithm, the motor drives the bracket to make the solar panels track the azimuth of the sun, increase the direct sunlight on the surface of the photovoltaic module, and increase the power generation.
