Description
1. Product Overview
SGMG-09ASA is a medium inertia permanent magnet synchronous AC servo motor belonging to Yaskawa Sigma-I SGMG series, rated for three-phase AC200V power input and specially matched with SGDB-10AN servo driver. It features smooth keyless shaft without built-in brake and is fitted with 15-bit serial absolute encoder. Adopting totally enclosed natural cooling design and complying with CE certification, this Japanese-origin motor delivers stable low-speed high torque and rapid dynamic response, widely used for equipment production and aftermarket spare replacement of legacy automation machines.
2. Electrical Parameters
The rated power is 0.85kW with rated speed at 1500rpm and maximum instantaneous speed up to 3000rpm. Continuous rated torque is 5.39N·m and peak transient torque reaches 13.8N·m for outstanding short-time overload performance. Rated working current is 7.1A and peak instantaneous current is 18.2A. The built-in 15-bit absolute encoder has 8192 pulses per revolution; with external backup battery, it keeps origin position after power cut and eliminates homing requirement. Rotor inertia is 12.8×10⁻⁴kg·m² and net weight is approximately 5.5kg, and medium inertia structure effectively suppresses vibration during acceleration and deceleration.
3. Mechanical and Environmental Specifications
Except the shaft penetration area, the motor has IP67 protection rating, and its winding applies Class F high temperature resistant insulation material with vibration level under 15μm. It withstands AC1500V voltage for one minute and maintains insulation resistance over 10MΩ under DC500V test condition. Flange mounting is the standard installation method. Normal working ambient temperature ranges from 0℃ to 40℃ and relative humidity keeps 20%~80% without condensation. Operating altitude shall not exceed 1000 meters; power derating is necessary for higher altitude use.
4. Key Product Advantages
Medium inertia rotor ensures sufficient low-speed torque and stable operation when load fluctuates. Absolute encoder preserves coordinate data after power off to shorten commissioning cycles. Fan-free fully enclosed natural cooling structure reduces failure risks and avoids dust intrusion. Standard version has no built-in brake and stops via driver’s electric braking function, while braked variant is SGMG-09ASAB. The encoder uses differential signal transmission for strong anti-electromagnetic interference capacity to fit harsh industrial site conditions.
5. Application Fields
It is commonly equipped on CNC machines, automatic packaging production lines, textile equipment, printing machines, electronic assembly devices, small robotic arms and auxiliary feeding units of laser cutting machines, serving as general replacement spare for original old Yaskawa servo systems.
6. Matching and Operation Notes
The motor must work with SGDB-10AN servo pack. Users need to set corresponding motor code, electronic gear ratio and control loop gains on driver before startup test. Power cables for U/V/W and shielded encoder wires should be laid separately to avoid signal interference. Spare motors need dry and ventilated storage between -20℃ and +60℃ away from damp and corrosive gas. Original factory warranty covers 12 months, excluding damages from improper wiring, overload or unauthorized structural alteration.
