The oil-sealed shaft design ensures long-term reliable operation in harsh industrial environments, effectively preventing dust, moisture, and other contaminants from entering the motor.
Technical Characteristics: In-Depth Analysis of Motor Performance
Absolute Encoder Technology
The absolute encoder equipped in the MHD115C-058-PG1-BA is one of its core advantages. Compared to traditional incremental encoders, the absolute encoder can provide accurate position information immediately upon system startup, eliminating the need for reference point searching. This feature is particularly important in applications requiring rapid startup and frequent starts and stops, such as high-speed packaging machinery and precision assembly equipment.
Oil-Sealed Shaft Design
The oil-sealed shaft employs a special sealing structure that effectively prevents external contaminants from entering the motor. This design offers significant advantages in industries with strict hygiene requirements, such as food processing, pharmaceuticals, and chemicals. Actual tests show that the oil-sealed shaft design can reduce the motor’s failure rate in harsh environments by more than 40%.
High Torque Density
The 115 frame size provides exceptionally high torque output. Through optimized electromagnetic design and the use of high-performance permanent magnet materials, this motor achieves a torque output far exceeding that of ordinary motors of the same size while maintaining a compact volume. This makes it particularly suitable for applications with limited space but requiring high torque, such as robotic joint drives and heavy-duty conveyor systems.
