ABB ESM13E-851-152-T1N0A00 Small 1 kW AC Servo Motor Unit

The ABB ESM13E-851-152-T1N0A00 is a high-precision 1 kW servo motor unit engineered for demanding industrial automation environments. This component functions as a critical actuator within motion control systems, providing the high-torque output and precise positioning required for rapid-cycle manufacturing processes. Procurement engineers select this 1 kw servo motor when balancing energy efficiency with consistent mechanical output in automated assembly lines. As a compact small ac servo motor, it integrates seamlessly into confined machine architectures while maintaining operational thermal stability under sustained loads. Maintenance professionals typically source this specific unit to replace legacy drives that exhibit increased heat dissipation or reduced position repeatability.

Product Type & Category Positioning

This component is classified as a permanent magnet synchronous AC servo motor, designed specifically for closed-loop motion control applications. It operates by converting electrical energy into precise mechanical rotation, controlled via an external servo drive that adjusts frequency and phase to achieve target velocity or torque. The product occupies the mid-range power tier within ABB’s ESM series, bridging the gap between low-wattage micro-drives and high-inertia heavy-duty motors.

Building on this classification, the motor utilizes a multi-pole rotor design to minimize torque ripple and maximize acceleration dynamics. Unlike induction motors, this unit maintains constant torque across its rated speed range, ensuring that machine throughput remains predictable regardless of load variations. It serves as a foundational element in multi-axis robotic systems and high-speed indexing tables where synchronization between axes is critical for production quality.

Technical Highlights

The ABB ESM13E-851-152-T1N0A00 incorporates a high-density winding configuration that reduces copper losses during peak acceleration phases. This design feature minimizes internal heat buildup, allowing the motor to operate at continuous rated torque without requiring external forced-air cooling systems.

Moreover, the unit utilizes a high-resolution 20-bit absolute encoder for real-time positional feedback. This allows the control system to detect position deviations at the sub-millimeter level, effectively eliminating the need for homing sequences after power cycles. The integration of high-grade rare-earth magnets further enhances the flux density, resulting in a compact form factor that optimizes cabinet space utilization in dense machine layouts.

Application Scenarios

Automated Packaging Lines: This motor manages the vertical movement of sealing heads at a rate of 120 cycles per minute with a positional tolerance of ±0.01 mm. It achieves a 15% reduction in power consumption compared to traditional induction-based actuators.   Precision CNC Tool Changers: The unit provides the rapid indexing torque necessary to rotate tool magazines within 0.5 seconds. Its robust construction resists vibrational fatigue, extending the mean time between failures (MTBF) for the tool-changing mechanism by approximately 20%.   Electronics Component Insertion: By maintaining a steady torque-to-inertia ratio, the motor allows for smooth component placement on high-density PCBs. The precise feedback loop ensures that the insertion force remains constant, preventing micro-fractures in delicate soldering joints during the assembly process.

Selection Recommendations

Suitable Application: High-speed gantry positioning systems where the duty cycle remains below 80% and the environment is free of caustic chemicals. This model excels in applications requiring high dynamic response and rapid directional changes (acceleration/deceleration<100 ms="">

FAQ

1. What are the specific dimensions and total weight of the ESM13E-851-152-T1N0A00?

The unit features a flange size of 130 mm by 130 mm and an overall length of approximately 185 mm excluding the shaft extension. It weighs 4.8 kg, making it suitable for compact mounting brackets in standard electrical cabinets. You can request a mechanical CAD drawing from our support team to verify clearance with your existing machine frame.

2. What is the standard lead time for this motor, and do you keep them in stock?

In-stock units are dispatched within 2 working days of order confirmation, while bulk orders exceeding 10 units require 5 to 7 business days for staging and quality testing. Beijing Zhongping Technology coordinates export logistics to ensure fast transit to your facility, providing tracking details upon departure.

3. Is the 20-bit absolute encoder compatible with existing third-party servo drives?

The 20-bit absolute encoder uses a high-speed serial protocol optimized for the ABB ESM series, requiring drive-side protocol compatibility for full positioning integration. If you intend to use a third-party controller, you must ensure its feedback option card supports this specific digital encoder interface. Our technical team can verify your drive model compatibility if you provide the drive specifications.

4. What is the current market price for this motor unit?

Prices for the ESM13E-851-152-T1N0A00 generally range from $1,800 to $3,200 USD depending on order volume and current international trade conditions. Market rates fluctuate based on raw material costs, tariffs, and currency exchange rates. For a binding formal quotation with tiered volume discounts, please contact Beijing Zhongping Technology directly.

5. Does this motor come with a warranty, and what is your return policy?

Every new unit includes a 12-month manufacturer warranty covering material and workmanship defects starting from the delivery date. If an operational failure occurs during the warranty period, submitting the serial number and a diagnostic error code initiates a rapid replacement claim. Unopened, non-defective returns are accepted within 30 days subject to prior authorization and a standard restocking fee.

6. What does the "N0" suffix indicate regarding the motor's mechanical brake configuration?

The N0 code confirms that this model is manufactured without an internal electromechanical holding brake, making it suitable for horizontal motion axes. For vertical or inclined load applications where gravity drop is a concern, a model with the B0 holding brake option must be selected.

7. Is the mounting flange dimensionally compatible with standard small-frame metric servomotors?

The ESM13E-851-152-T1N0A00 features an IEC standard metric mounting flange with precision pilot diameters and tapped holes for drop-in mechanical replacement. This enables straightforward substitution into existing automation machinery without requiring custom adapter plates.

8. What ingress protection (IP rating) does this 1 kW motor offer against industrial dust and oil mist?

The motor carries a standard IP65 ingress protection rating, shielding internal windings and encoder optics from airborne dust, ambient humidity, and water splashing. For applications exposed to continuous cutting fluid mist or oil spray, installing an optional shaft oil seal is recommended.

9. Does this 1 kW motor require an external forced-air cooling fan when mounted in enclosed spaces?

No external forced-air fan is required under standard S1 continuous operation, as operational heat is dissipated via natural convection and flange conduction. However, ambient air temperature surrounding the motor housing must be maintained below 40°C to prevent thermal power derating.

10. What is the Minimum Order Quantity (MOQ) and standard payment terms for single-unit purchases?

The Minimum Order Quantity is 1 unit, with payment accepted via international wire transfer (T/T), major credit cards, or letter of credit (L/C). Full payment confirmation is required prior to export dispatch for standard commercial orders.
