With the continuous advancement of industrial manufacturing technology, cutting equipment is developing towards high precision, high efficiency, low noise and intelligence. Especially in high-strength use scenarios such as metal processing, composite material cutting, and building formwork customization, higher requirements are put forward for the performance of the motor system.
Our customers are a European-based manufacturer of smart cutting equipment that specializes in custom cutting solutions for building materials, aluminum profiles and composite sheets. They are developing a new generation of smart cutting machines, with the goal of improving market competitiveness and meeting users' needs for stable operation, precise control and low maintenance costs.
1.Overheating under high-load operation: Existing motors couldn’t handle extended cutting cycles without thermal failure.
2.Unstable torque: When cutting layered or high-resistance materials, the torque output would fluctuate, resulting in uneven cutting quality.
3.Strict spatial constraints: The internal motor chamber was limited in size and required non-standard shaft and mounting options.
4.Low-noise requirement: The motor needed to meet a noise limit of ≤ 40dB during full-load operation.
5.Industrial protection level: The working environment was dusty and prone to oil splashes, requiring a durable, sealed motor structure.
To address all of the client's challenges, we delivered a customized high-performance brushless DC motor system, designed specifically for industrial cutting applications.
