What are High Power Rotators?

NSI-MI Technologies' High Power Rotators are built to handle heavy loads, high speeds, and endure harsh outdoor environments. They feature high structural and drive safety factors and are equipped with EMI gaskets to minimize electromagnetic interference, making them suitable for high RF power applications. Standard features such as stow pins, temperature control, customizable colors, and an automatic lubrication system ensure reliable performance for critical operations. The large thru-hole accommodates rotary unions, slip rings, rotary joints, and fiber optics, to allow for continuous, uninterrupted rotation. Each rotator comes equipped with an API-enabled position controller.

Built for harsh environments

NSI-MI High Power Rotators are specially designed for lasting performance in extreme operating conditions. All rotators support very wide temperature ranges and up to 100% humidity, making them ideal for outdoor environments. The optional temperature control system includes a heater module equipped with a built-in thermostat and fan to heat the internal volume of the rotator when ambient temperatures drop below freezing. Additionally, a thermostatically controlled fan evacuates warm air from the positioner if the internal temperature exceeds a programmable threshold. The optional lubrication system ensures that the system will remain operational in remote locations for mission critical applications. Some models have been designed with support for up to 95 km/h (60 mph) wind speeds for high altitude sites. Finally, MEC-HPR can be delivered in custom colors to maximize safety and discretion for outdoor applications.

Through Path Options
Thru-Contacts electrical path 
Each rotator is designed to support the integration of customer-furnished rotary unions, slip rings, rotary joints, and fiber optics. This flexible approach allows you to run all necessary electrical, RF, hydraulic, exhaust, or liquid cooling lines safely through the positioner to support continuous rotation for mission critical applications. Contact NSI-MI for available standard slip ring assemblies.
Convenience & Protection Options
Stow Pin 
SP1 – Stow-Pin
Adds manual stow-pin and mating receptacle to protect the positioner’s drive-train in susceptible environments such as high wind-gust exposure in outdoor environments and high-load pick-up mode applications. Includes electrical interlock circuit for disabling the servo system when stow-pin is inserted. Default position is zero (0) degrees. Alternate stow-pin angle locations are available upon request.
Lubrication System 
ALS1 – Lubrication system
The automatic lubrication system is designed to inject grease into the slewing ring bearing ports and ring gear points at regular intervals ensuring continuous and maintenance-free operation.
Riser 
RS1 – Riser
Adds a structural riser below the positioner for applications requiring accurate centering from a platform, outdoor silo applications, and various customer requested heights. Risers are designed to withstand the full capacity of the mated positioner and are tailored to your required height. Available features include access hatches, custom color, internal shelving, and external and internal ladders.
Temperature control system 
HT1 – Temperature control system
A heater module equipped with a built-in thermostat and fan heats the internal volume of the positioner when ambient temperatures drop below freezing. Additionally, a thermostatically controlled fan evacuates warm air from the positioner if the internal temperature exceeds a programmable threshold.
