Product Description:
The Pacific Scientific's Servo motor S32HNBA-RNVM-00 is designed for controlled motion tasks of industrial automation. It comes with a square housing that measures 85.9 mm to allow installation in compact assemblies. This motor provides a steady stall torque output of 3.8 Nm. It reaches a peak torque of 11.2 Nm.
The S32HNBA-RNVM-00 servo motor has a static holding torque of 0.15 Nm and a damping value of 0.039 Nm/Krpm. The rotor carries a low angular mass of 0.000032 kg·m² to support quick changes in motion. Its thermal load capacity is rated at 0.97 °C/W. The heat buildup time of this S32 servo motor is 24 minutes. The net weight of the motor is 4.9 kg. This gives the motor a firm and balanced structure for fixed mounting. The winding inductance across lines is measured at 6.3 millihenries. The S32HNBA-RNVM-00 servo motor uses Winding H for its electrical layout. Its torque conversion ratio is 0.84 Nm/A. The voltage feedback value is 87 V per radian per second. The continuous current during stall conditions is 6.9 A. The highest current drawn by the motor is 20.7 A. The electrical resistance across lines is 2.1 ohms when cold and 3.2 ohms when warm.
The total S32HNBA-RNVM-00 servo motor length is 235.9 mm with the brake system. The mounting setup features 7.0 mm diameter holes placed on a 100 mm bolt circle. The shaft measures 14 mm in diameter and has a minimum extension length of 22 mm. This servo motor includes a frameless resolver for motion sensing. The sensor supports motor commutation, position tracking, and speed data output. It is rated to handle temperatures up to 155 °C. The sensor adds minimal rotational load and around 0.036 kg to the total unit weight.
Frequently Asked Questions about S32HNBA-RNVM-00:
Q: What is the role of voltage feedback in S32HNBA-RNVM-00 servo motor?
A: The S32HNBA-RNVM-00 servo motor’s high voltage feedback ratio enhances velocity loop sensitivity. It demands precise encoder scaling for smooth control under high-speed loads.
Q: Why does S32HNBA-RNVM-00 servo motor include a frameless resolver?
A: The S32HNBA-RNVM-00 servo motor’s frameless resolver minimizes mass and friction. It allows accurate feedback while maintaining dynamic efficiency in lightweight assemblies.
Q: How does S32HNBA-RNVM-00 servo motor handle thermal buildup?
A: The S32HNBA-RNVM-00 servo motor has a 24-minute thermal rise delay. This allows temporary overloads but requires proper mounting to avoid long-term saturation.
Q: Why is damping value relevant in S32HNBA-RNVM-00 servo motor applications?
A: The S32HNBA-RNVM-00 servo motor’s damping value affects oscillation suppression. Low damping requires well-tuned control loops, especially in high-speed, low-friction mechanisms.
Q: What challenges arise from 3.2-ohm warm resistance in S32HNBA-RNVM-00 servo motor?
A: The S32HNBA-RNVM-00 servo motor’s rising resistance at heat saturation reduces current throughput. Drives must compensate or performance will degrade under prolonged load.
