Purpose-Engineered Perfection

Designed in the USA specifically for solar tracking by a team that has produced over two million actuators, our drives are created and tested to last the life of the plant.

Full Range of Sizes and Options

Our solutions are optimized for today’s high-density tracker designs—and can be easily customized to meet the requirements of your specific applications.

Tech & Products

The #1 choice for motion control solutions for the solar tracker industry

Trusted by more solar tracker brands to deliver superior tracking performance, Kinematics’ drives are designed for the rigors and demands of utility-scale solar tracking applications unlike generic actuator alternatives.

Kinematics ST™ Series

The next-gen ST series is the most reliable solar tracker drive ever. Featuring an exclusive maintenance-free, grease-free dry bearing design that delivers 20-50% more holding torque than our HE series, the ST Series allows you to use a smaller size for the same application resulting in cost savings without sacrificing performance. It features a corrosion and UV resistant design, and is environmentally-sealed (IP65).

The ST6 delivers over 25% more max holding torque (20 kN-m) than the HE6 series, in the same 6″ (152mm) package. It features 4 kN-m output torque.


The ST7 offers the same max holding torque in a 7″ (190mm) package as the HE8. It features 6.5 kN-m output torque.


The ST8 delivers a whopping 45 kN-m max holding torque rating in an 8″ (210mm) package. It features 8 kN-m output torque.


The ST9 is our largest solar tracker actuator for the most demanding applications with over 60 kN-m of holding torque. It features 12 kN-m output torque.

Kinematics HE™ Series

More solar trackers bank on the HE series than any other drive on the market. Designed exclusively for solar trackers and fully customizable to application requirements, the HE family of fully-enclosed vertical drives is designed to deliver the highest performance.


Optimized for 1P and internal row structures, the HE6 features a 6″ diameter (152mm) raceway and a max holding torque rating of 15 kN-m and 2 kN-m torque output.


Ideal for a variety of tracker applications, the HE8-51 features a 7.5″ diameter (190mm) raceway and a max holding torque rating of 28 kN-m and 4.8 kN-m torque output.


Rugged design and high max torque makes the HE8-61 ideal for outside rows or demanding environments. This drive features an 8″ diameter (210mm) raceway and a max holding torque rating of 36 kN-m and 7 kN-m torque output.


Our largest solar tracker specific actuator designed for the most demanding applications. This drive features a 9″ diameter (230mm) raceway and a max holding torque rating of 40 kN-m and 9 kN-m torque output.
