SGMBH Sigma II

Rated Output: 22kW, 30kW, 37kW, 45kW, and 55kW

The SGMBH servomotor series has an internal permanent magnet (IPM) design which reduces rotor inertia. These servomotors are well suited for highly dynamic, high power applications such as hydraulic system replacement. There are 5 sizes from 22 kW to 55 kW providing up to 6,120 lb-in (700 Nm) of peak torque. 400 volt windings are available with rated speeds of 1,500 rpm and maximum speeds of 2,000 rpm. A 131,072 ppr incremental serial encoder is standard. Options include a 131,072 ppr absolute encoder, shaft seal, and holding brake.

Design Features:

1. Compact

• Internal Permanent Magnet (IPM) construction reduces rotor inertia and permits high speeds
• High flux density neodymium iron boron permanent magnets reduce rotor size
• 3 frame sizes with flange widths from 9.84 to 13 inches (250 to 330 mm)

2. High Performance

• High torque-to-inertia ratio compared to induction servo designs
• Skewed magnets reduce cogging torque for smooth motion at low speed and short settling times
• Medium inertia rotor is ideal for optimized load matching
• Peak torque can be maintained for up to five seconds
• Rated speed of 1,500 rpm, max speed of 2,000

3. High-Resolution Serial Encoder

• 131,072 ppr incremental encoder standard 1
• 131,072 ppr absolute encoder optional 1
• Amplifier automatically recognizes the motor and optimizes parameters
• Error checking eliminates lost motion from electrical noise
