Breakthrough with Brushless Motor Technology on UWT NivoBob® NB 3000

Advanced Level Measurement Solution for Heavy-Duty Industrial Applications

In heavy industrial environments such as cement plants, fly ash handling systems, mining, and bulk material storage, level measurement must be performed continuously and reliably. Traditional mechanical components often face wear and tear, leading to frequent maintenance and unexpected downtime.

To address these challenges, UWT has integrated advanced brushless motor technology into the NivoBob® NB 3000, delivering a new standard of durability, performance, and long-term reliability in electromechanical level measurement.

1. Extremely Long Operational Lifetime

Unlike conventional brushed motors, where carbon brushes are subject to continuous mechanical wear and are considered natural consumable parts, brushless motors completely eliminate physical contact between moving electrical components.

As a result, the brushless motor used in the NivoBob® NB 3000 offers:

Up to 500,000 measuring cycles, significantly exceeding the lifespan of standard motor technologies
Continuous operation of up to 60,000 operating hours, enabling reliable performance over decades under standard conditions
No degradation caused by brush wear, ensuring consistent measurement accuracy throughout the device’s lifetime

This makes the NivoBob® NB 3000 an ideal choice for plants where maintenance access is limited or costly.

2. High Measurement Frequency for Continuous Process Monitoring

Thanks to its superior thermal management and friction-free operation, the brushless motor enables:

Frequent and repeated measurements without the risk of overheating
Stable performance even under high-duty cycles
Optimized level monitoring in silos and storage vessels where real-time material level updates are critical

This capability is particularly valuable in applications requiring dense measurement intervals and fast process feedback.

3. High Performance and Outstanding Reliability

The brushless motor delivers stable and consistent torque, allowing smooth lifting and lowering of the sensor weight even in:

Dusty environments
Heavy bulk materials
Challenging silo geometries

This significantly reduces the risk of cable jamming or measuring tape damage.

In addition, the integrated motor driver uses intelligent control algorithms to:

Detect overload conditions
Identify mechanical obstructions early
Automatically protect the measuring system from damage

These features ensure safe, reliable operation and long-term measurement stability.

4. Significant Reduction in Maintenance Costs

One of the most important advantages for plant operators and maintenance managers is cost efficiency over the entire lifecycle:

No carbon brushes to replace, eliminating spare part and labor costs
Reduced maintenance intervals and fewer service interventions
Minimized unplanned downtime, keeping production processes running smoothly

By eliminating common failure points, the brushless motor helps optimize total cost of ownership (TCO).

5. Designed for High Temperatures and Harsh Environments

The brushless motor on the NivoBob® NB 3000 is engineered to withstand demanding industrial conditions:

Ambient operating temperatures up to +60 °C
Optional high-temperature sensor capability up to +250 °C
Robust dual housing design, effectively isolating the motor from dust, heat, and harsh process conditions

This construction ensures maximum protection and long-term reliability, even in extreme applications.

A Future-Proof Investment in Level Measurement

The brushless motor technology integrated into the UWT NivoBob® NB 3000 represents a major advancement in electromechanical level measurement. It combines durability, precision, and intelligent protection to meet the highest industrial demands.

For plants seeking high measurement accuracy, minimal maintenance, and long-term operational efficiency, the NivoBob® NB 3000 with brushless motor is a future-proof investment.
