Broad Material & Application Compatibility

Works with plastic, copper, brass, iron, carbon steel, aluminum, high-grade steel, premium stainless steel and titanium. Non-standard sizes and special bevel profiles are customizable. Widely used for pre-weld pipe preparation in petroleum, petrochemical, food-beverage-dairy, pharmaceutical, metallurgy, water treatment, shipbuilding and power industries.

Technical Specifications

Introduction to Servo-Driven Motor

The servo motor for servo-driven external clamp cutting chamfering machine offers prominent advantages. The servo control system delivers high-precision closed-loop regulation, providing better dynamic response, positioning accuracy and stability during cutting compared with conventional drives. Energy-efficient and low-maintenance, it cuts operating costs, supports automated continuous production, and enhances equipment adaptability and reliability under harsh working conditions.

1. This motor features an increased-safety explosion-proof construction. A series of reliable measures are adopted to suppress sparks, electric arcs and hazardous high-temperature conditions, enabling safe operation in Zone 2 explosive hazardous areas.

2. It adopts brushless excitation, equipped with a rotating rectifier disc and static excitation cabinet for reliable excitation control system performance. Positive-polarity slip-dependent excitation switching is accurate without shock loads. The excitation system delivers dependable out-of-step protection and strong re-synchronization capability. Reasonable circuit design prevents abnormal heating of discharge resistors during operation, with a wide adjustment range for excitation current.

3. The synchronous main motor, AC exciter and rotating rectifier disc are coaxially arranged. The rectifier disc can be installed either between the main motor and exciter, or on the outer side of the bearing housing.

4. Enclosure protection rating: IP54.

5. Class-F insulation structure is applied; winding temperature rise is evaluated in accordance with Class-B criteria.

6. Fitted with an increased-safety anti-condensation heater, fixedly mounted inside the bottom motor cover to provide heating and moisture protection during shutdown.

7. High-grade raw materials are selected. Sufficient margins are reserved for both electrical and mechanical calculations to satisfy operational reliability and temperature-control requirements for increased-safety motors.

8. Comprehensive operational monitoring is implemented: increased-safety self-balancing current transformers for differential protection are fitted within the main terminal box. Working and spare Pt100 platinum thermal resistors are embedded in stator windings. Local temperature indicators and remote-signal terminals are provided for both end pedestal-type plain bearings.
