YASKAWA SGMAS-02ACA413 High-Response Sigma II Series Servo Motor for Precision Automation

The YASKAWA SGMAS-02ACA413 is a 200-watt, low-inertia AC servo motor from Yaskawa’s renowned Sigma II series, engineered for high dynamic response and precision in compact automation systems. Featuring an integrated 2500-pulse-per-revolution incremental encoder and robust IP65-rated construction, it delivers smooth motion control for applications demanding rapid acceleration, accurate positioning, and long-term reliability.

Designed to pair seamlessly with Yaskawa SGDH-series servo amplifiers, the YASKAWA SGMAS-02ACA413 combines Japanese engineering excellence with industrial ruggedness—making it a go-to choice for OEMs in packaging, electronics assembly, and machine tooling.

Application Scenarios

In a high-speed pharmaceutical blister packaging line in Germany,repeated misfeeds at 300 cycles/minute traced back to inconsistent servo response in the indexing mechanism.After replacing a generic 200W motor with the YASKAWA SGMAS-02ACA413,engineers achieved±0.02 mm repeatability and eliminated jams—even during 16-hour continuous shifts.The motor’s ultra-low rotor inertia(0.27×10⁻⁴kg·m²)enabled faster settling times,while its minimal cogging torque ensured smooth film transport.In this case,the YASKAWA SGMAS-02ACA413 wasn’t just a motion component—it became the enabler of throughput stability and product quality.

Technical Principles and Innovative Values

Innovation Point 1:Ultra-Low Inertia Rotor Design

The YASKAWA SGMAS-02ACA413 features a specially balanced rotor with minimized moment of inertia,enabling acceleration rates up to 100,000 rpm/s—ideal for rapid start-stop applications like labeling heads or delta robots.

Innovation Point 2:Advanced Magnetic Circuit for Minimal Cogging

Through optimized stator lamination and magnet placement,Yaskawa reduced cogging torque to<1%of rated torque,ensuring smooth low-speed motion critical for glass handling or optical alignment stages.

Innovation Point 3:Integrated Thermal&Overload Protection

Built-in thermal sensors communicate real-time winding temperature to the SGDH drive,enabling intelligent current limiting—extending motor life without external protection relays.

Innovation Point 4:Universal Mechanical Compatibility

The YASKAWA SGMAS-02ACA413 uses standardized shaft dimensions(14 mm diameter,keyway)and flange mounting,allowing drop-in replacement in legacy systems originally using Mitsubishi or Panasonic servos.

Application Cases and Industry Value

At an Asian electronics manufacturer assembling smartphone cameras,micro-lens alignment required sub-micron precision at high cycle rates.The YASKAWA SGMAS-02ACA413,paired with an SGDH-02AE amplifier,drove a linear stage with<±1µm positioning error over 10 million cycles.Its consistent torque linearity prevented lens tilt during insertion—a defect that previously caused 3%yield loss.Post-integration,first-pass yield rose to 99.8%,directly attributable to the motor’s mechanical and electrical stability.

In another case,a North American bakery automated bag sealing using three-axis gantries powered by YASKAWA SGMAS-02ACA413 motors.Despite flour dust and washdown conditions,the IP65 rating and stainless steel shaft prevented contamination ingress.After two years of 24/7 operation,zero motor failures were recorded—validating Yaskawa’s claim of>20,000 MTBF in food-grade environments.

Installation,Maintenance,and Full-Cycle Support

Installing the YASKAWA SGMAS-02ACA413 requires secure flange mounting to prevent resonance,proper grounding of the motor frame,and use of shielded twisted-pair cables for encoder signals(with shield grounded at drive end only).Ensure ambient temperature stays below 40°C for continuous operation;above this,derate output torque per Yaskawa’s thermal curves.If used with a brake,verify release timing aligns with drive enable signals to avoid mechanical stress.

Routine maintenance is minimal—no brushes to replace—but periodic inspection of shaft runout,bearing noise,and connector integrity is recommended in high-vibration environments.The motor’s sealed bearings are lubricated for life,eliminating re-greasing needs.Should an encoder fault occur,the SGDH drive will log error codes(e.g.,A.81),enabling rapid diagnostics without motor disassembly.

We supply only genuine YASKAWA SGMAS-02ACA413 units sourced through authorized distribution channels,each verified for nameplate compliance,encoder signal integrity,and insulation resistance(>100 MΩat 500 VDC).Every motor includes original test certificates and is backed by 18 months of warranty.Our engineering team provides pairing guidance with SGDH drives,tuning assistance for resonance suppression,and cross-reference support for legacy Sigma I upgrades.
