Detailed Description – Yaskawa Servo Motor Portfolio
1. Σ-7 Series – Flagship High-Performance Servo
The Σ-7 Series represents Yaskawa’s latest generation of AC servo motors. It delivers industry-leading speed-loop gain of 70Hz, nearly double that of the previous Σ-V series .
Key Features:
✓ 24-bit high-resolution encoder – 16.7 million pulses per revolution for ultra-precise positioning
✓ High speed response – Speed-loop response frequency up to 3.2kHz
✓ Energy saving – Reduced power consumption through improved motor efficiency
✓ Safety – Functional Safety (FSoE) support on select models
2. Rotary Servo Motors – By Inertia
Yaskawa organizes its rotary servo motors by inertia class, allowing engineers to match the motor to the load dynamics .
Low Inertia – SGM7A Series
Designed for applications requiring rapid acceleration and deceleration. The low rotor inertia minimizes settling time. Power ranges from 50W to 7kW .
Medium Inertia – SGM7J / SGM7G / SGM7P Series
Medium inertia motors provide higher torque per unit of current, making them ideal for direct coupling to loads with higher inertia . The SGM7G focuses on high torque density, while the SGM7P offers a flat, compact form factor for tight spaces .
3. Direct Drive Servo Motors – Σ-7 Series
Direct drive motors eliminate mechanical transmission components (gearboxes, belts). This results in zero backlash, high stiffness, and precise positioning .
| Type | Series | Torque Range | Best For |
|---|---|---|---|
| Outer Rotor | SGM7D | 1.30 – 240 N·m | Direct coupling to rotary tables |
| Inner Rotor (Coreless) | SGM7F | 2.00 – 35.0 N·m | Smooth, cogging-free rotation |
| Inner Rotor (Coreless) | SGM7E | Small – medium | Semiconductor, precision assembly |
4. Linear Servo Motors – SGLG / SGLT / SGLF2 Series
Yaskawa linear servo motors provide direct linear motion without rotary-to-linear conversion, achieving high speed, high acceleration, and sub-micron positioning accuracy .
| Series | Force Range | Motor Type |
|---|---|---|
| SGLG | 12.5N – 750N | Coreless |
| SGLT | 130N – 900N | Iron core |
| SGLF2 | 45N – 1680N | High-thrust, iron core |
Key Technology Features
SigmaWin+ Software – Easy Setup
Yaskawa’s SigmaWin+ PC-based software significantly reduces tuning time.
Tuning performance improvements over previous models:
✓ Advanced Auto-Tuning – Adjustment time reduced to 1/15 of conventional methods
✓ Single-Parameter Tuning – Adjustment time reduced to 1/10
✓ Quick Tuning – Settling time of 100–150ms with no manual adjustments required
Absolute Encoder – No Battery Required (Σ-7)
The Σ-7 Series utilizes an absolute encoder that eliminates the need for a backup battery. Position data is retained even when power is removed, simplifying homing procedures and reducing maintenance .
MECHATROLINK-III Communication
Yaskawa servo motors and drives support MECHATROLINK-III, a high-speed motion control network that provides real-time command transmission and feedback .
Functional Safety (FSoE)
Select Σ-7 models support FailSafe over EtherCAT (FSoE), enabling integrated safety functions without external safety relays .
Selection Guide – Understanding the Naming Convention (Yaskawa Σ-7 Series)
Yaskawa servo motor part numbers follow a structured logic. Understanding the coding helps rapid selection .
