As the “power heart” of modern industry, the technological sophistication and performance of industrial motors directly influence production efficiency and the pace of green transition. Recently, Northern Jiaxuan unveiled (opens in a new tab) a suite of industrial energy-saving “black technologies,” offering disruptive solutions tailored for high-energy-consumption belt conveyor systems.

Permanent Magnet Semi-Direct Drive Retrofit

Reshaping transmission systems for energy savings and reduced consumption.

Traditional factory belt conveyors frequently suffer from oil leakage, excessive noise, strong vibration, and recurring maintenance issues that increase operational costs and slow production. Northern Jiaxuan’s “Permanent Magnet Semi-Direct Drive Retrofit” solution delivers clear advantages in performance, energy efficiency, and cost reduction.

The system removes gear reducers and couplings entirely, allowing a low-speed permanent magnet motor to drive the drum directly. This simplifies the transmission chain, significantly boosts efficiency, and reduces energy losses.

The motor’s power factor reaches 0.96, eliminating the need for external reactive-power compensation. Weighing 7.5–8.5 tons, it can be installed using existing cranes without changes to plant infrastructure. Under equal load, operating current drops 22%, active power decreases by 38 kilowatts, and maintenance requirements decline substantially—reducing both energy consumption and lifecycle costs.

Permanent Magnet External Rotor Drum Motor

Advancing green, low-carbon development with integrated belt-drive solutions.

More advanced than semi-direct drives, Northern Jiaxuan’s external-rotor permanent magnet drum motor integrates the motor and drum into a single intelligent unit. With 150 units already deployed in mining and metallurgical operations, the technology emphasizes standardized design, modular assembly, and rapid deployment.

According to the media of Northern China Rare Earth, the system delivers 25%–30% energy savings across all load conditions, cuts maintenance frequency by half, improves speed-control accuracy to ±0.5%, and limits multi-motor synchronization error to ≤0.1%, extending conveyor belt life by 20%. Features include predictive maintenance, energy management, coordinated control, and full lifecycle traceability.

Permanent Magnet Intelligent Direct Drive

Achieving cost reduction and efficiency gains across industrial scenarios.

Permanent magnet direct-drive motors overcome the chronic weaknesses of traditional high-energy-use industrial equipment. Built around three pillars—variable-frequency speed control, low-speed high-torque direct drive, and integrated motor-load design—the technology delivers high efficiency, reduced failure rates, lower energy use, smaller installation footprint, and adaptability to complex applications such as pumps, crushers, mixers, conveyors, and cooling systems.

When paired with Northern Jiaxuan’s “Mechatronics Guardian” intelligent diagnostic platform, the system replaces manual inspection with real-time monitoring of vibration, temperature, speed, and pressure. Cloud-based analytics identify faults early, cutting downtime by 70%, extending equipment life by 10–20%, and reducing spare-parts consumption by half.
