Product Superiority
Materials
The long shaft is forged from high-strength carbon steel, making it resistant to deformation under high-temperature and heavy-load operating conditions and providing excellent torsional rigidity. The internal windings are made of high-quality heat-resistant insulation material, which slows down insulation aging. The cast iron housing offers excellent heat dissipation and corrosion resistance.
Manufacturing Process
The motor shaft core undergoes precision CNC machining, and every finished motor undergoes strict dynamic balancing calibration. Prior to delivery, each motor passes high-temperature aging tests as well as no-load and loaded operation tests.
Specification Advantages
A wide range of power options is available, and shaft lengths can be customized; the motors support both high axial thrust loads in the vertical direction and radial loads in the horizontal direction. The protection rating can be upgraded upon request.
Competitive Advantages
We provide a one-stop solution for vertical and horizontal high-temperature, long-shaft applications, eliminating the need for customers to purchase two different motor models. As the original equipment manufacturer, we offer technical drawing support, after-sales maintenance guidance, and customization services for bulk orders. Rigorous end-to-end quality control effectively maximizes equipment uptime for end users.
Application Scenarios
- High-temperature circulation fans for tempering furnaces, drying ovens, and reflow soldering equipment
- Special-purpose motors for glass decaling equipment, wave soldering, and tunnel furnaces
- High-temperature agitators and mixing equipment
- High-temperature circulation pumps and specialized process fan systems
- Heat treatment, drying lines, and high-temperature test chambers

FRQ
Q1: What is the maximum ambient temperature at which this motor can operate?
A: This motor features Class F heat-resistant insulation and can operate continuously at ambient temperatures up to 400°C. For environments with higher temperatures, we offer customized insulation and cooling solutions.
Q2: Can the shaft length be customized?
A: Yes. The shaft length, diameter, and keyway dimensions can all be customized according to your equipment drawings. In addition, we offer standard extended-shaft versions for common fan and pump applications.
Q3: Is this motor compatible with variable frequency drives (VFDs)?
A: Yes. This motor supports operation with VFDs and is suitable for variable-speed applications. If frequent low-speed or high-frequency operation is required, we recommend upgrading to a dedicated VFD motor.
