IP66 Multi-Tooth Worm Gear Dual Axis Slewing Drive With Stepper
Motor For PV Solar
Gear Dual Axis Slewing Drive Description
The slew drives come with an IP66 rated protection grade, which
protects the drive from environmental conditions as well as dirt,
sand, dust and even water. The drive is designed in such a way that
huge loads can be carried with compact form. The gears used in the
assembly could be hardened, so that they provide maximum durability
and longer life.

Stepper Motor
Revealing the six benefits of stepper motors with planetary gearbox
People know that stepper motors have been widely used, it can
control the number of pulses to control the amount of angular
displacement, so as to achieve the purpose of accurate positioning,
but do you know the benefits of stepper motor? Here are some
benefits:
1. The angle of the motor rotation is proportional to the number of
pulses.
2. When the motor stops, it has the maximum torque (when the
winding is excitation).
3. Excellent start-stop and reverse response.
4. Due to the absence of brushes, high reliability, so the life of
the motor depends only on the life of the bearing.
5. Only the load directly connected to the motor shaft can also be
very low-speed synchronous rotation.
6. Because the speed is proportional to the pulse frequency, so
there is a relatively wide speed range.
