Selin Systems 7AL-2700-20RS-B เซอร์โวมอเตอร์

Selin Sistemleri, also known as Selin Systems, is a professional motion control manufacturer based in Europe. It mainly engages in servo drive systems, stepper motors and supporting industrial automation products. ของมัน เซอร์โวมอเตอร์ are widely used on production lines across Europe and the Middle East. In China, these products are mostly imported together with complete equipment, and limited official technical documents are publicly available.

7AL-2700-20RS-B is a general-purpose AC permanent magnet synchronous servo motor from Selin 7AL Series. It is factory-fitted with a resolver for signal feedback and a power-off brake. Designed as a medium-to-low inertia industrial servo motor with high reliability, it is applicable for positioning and torque control in automotive component production, เครื่องจักรบรรจุภัณฑ์, material handling and other fields.

4. การจับคู่ & คู่มือการเลือก

4.1 ไดรฟ์ที่เข้ากันได้

It is recommended to use the matching servo drives of Selin Sistemleri. The drive must support resolver communication protocol and be rated for 0.75kW. If the original drive is unavailable, general-purpose servo drives with resolver support can be used as alternatives. Encoder phase auto-tuning must be completed after replacement.

4.2 Parameter Verification Methods

1. Check the metal nameplate on the motor side to confirm rated voltage, พลัง, แรงบิด, ความเร็ว, insulation class and other rated data.
2. Count cable sets: Brake-equipped motors have 3 cable sets (สายไฟ, resolver feedback cable, brake cable).
3. Measure flange mounting hole pitch, spigot diameter and shaft diameter to verify mounting compatibility.

4.3 คำแนะนำรูปแบบทางเลือก

If the original model has long lead time or high cost, equivalent servo motors with identical mounting dimensions and performance are recommended as follows:

5. Standard Wiring Definition

General wiring definition for 80mm frame servo motor with resolver and brake (Wire colors may vary among manufacturers. Verify before wiring).

6. การใช้งานทั่วไป
7. Automotive Component Production Lines: Manipulators for material loading/unloading in stamping processes, positioning of welding fixtures, station control on conveyor lines. Resolver feedback adapts to workshop conditions with vibration and oil contamination.
8. Vertical Lifting Mechanisms: Z-axis modules, elevators and stackers. The brake prevents load falling when power fails.
9. บรรจุภัณฑ์ & เครื่องจักรการพิมพ์: Feed shafts, tension control and cutting positioning. Medium-to-low inertia design meets requirements for frequent high-speed start and stop.
10. General Automation Equipment: High-precision positioning for feed axes of machine tools, textile machinery and ceramic machinery.

8. การดำเนินการต้องห้าม & กฎความปลอดภัย
9. Electrical Rules: Do not apply voltage beyond rated value. Do not run power cables and feedback cables in the same conduit. Do not plug/unplug feedback connectors when powered on. Do not reverse brake power polarity.
10. Mechanical Rules: Do not strike the motor shaft radially. Do not operate continuously beyond rated torque and speed. Do not apply radial/axial load exceeding the allowable limit on the shaft end.
11. Environmental Rules: Do not use in flammable, explosive or highly corrosive atmosphere. Do not immerse the motor in water or expose it to direct water spray for a long time. The shaft extension is not waterproof.
12. Brake Rules: Do not activate the brake while the motor is running at high speed. The brake is only for static holding after shutdown, not for dynamic braking.
13. Commissioning Rules: Resolver phase auto-tuning is mandatory after drive replacement. High-speed operation is forbidden before phase calibration, otherwise the motor may run out of control and get damaged.

รายการรุ่นที่สมบูรณ์ & Introduction of Selin Sistemleri 7AL Series Servo Motors

> Document Note: Selin Sistemleri is a regional industrial motion control manufacturer with limited publicly released full-range catalogs. The content below is compiled according to the brand’s unified coding rules and general specification standards of European servo motors. The naming rule is fully consistent with 7AL-2700-20RS-B, for model verifcation and replacement reference. Refer to official manuals or motor nameplates for exact rated parameters.

1. ภาพรวมซีรีส์

The 7AL Series is Selin’s core line of 3-phase permanent magnet synchronous AC servo motors. Featuring medium-to-low inertia and wide compatibility, the power range covers 0.05kW ~ 2.2kW. Multiple feedback options are available, including incremental encoder, resolver and absolute encoder, together with optional power-off brake. This series is widely applied in packaging machinery, การจัดการวัสดุ, automotive component production lines and general automation equipment.

2. Unified Naming Rule

Fixed format: `7AL [Torque Code] [Speed Code][Feedback Code] [Configuration Suffix]`

3. รายการรุ่นเต็ม

Classified by frame size and torque grade:

3.1 60mm Frame (Low Torque Range)

3.2 80mm Frame (Medium Torque Range, โมเดลหลัก)

3.3 90/110mm Frame (High Torque Range)

4. Matching Drive Series

All 7AL series servo motors are compatible with Selin ASD-7A series servo drives, matched by power rating:

0.1~0.2kW: ASD-7A-0123

0.4~0.75kW: ASD-7A-0423 / ASD-7A-0723

1.0~1.5kW: ASD-7A-1023 / ASD-7A-1523

> The drive must match the motor feedback type. Drives with resolver interface are required for resolver-equipped motors. Encoder phase auto-tuning is required when using third-party drives.

5. Model Verification Methods
6. Check the metal nameplate on the motor body to confirm rated voltage, แรงบิด, ความเร็ว, feedback type, insulation class and other parameters.
7. Count cable sets: 3 sets for brake-equipped motors (สายไฟ, feedback cable, brake cable); 2 sets for non-brake models.
8. Measure flange hole pitch, spigot diameter and shaft diameter to determine frame size: 60mm frame = 60mm flange; 80mm frame = 80mm flange; 90mm frame = 90mm flange.
