Product Description:
This PMB31D-20114-03 brushless servomotor supplied by Pacific Scientific has a robust design with a NEMA mounting option. The motor’s neodymium-iron-boron magnets help it to deliver high torque. This product is ideal for use where high torque and acceleration are required. The device has no mechanical commutation support as there are no brushes. This unit finds its use in manufacturing industries in textile processing machines, printing presses, and packaging and labeling machines. It requires a tuning to be carried out to meet the specific load and application requirements. The motor needs to be cooled down after its use.
This product handling is recommended by trained personnel. The device should neither be dropped nor tipped during its transport. This unit-related feedback is achieved by a digital encoder with a high resolution. Its bearings’ long life is ensured by their double shielding. The motor offers support for a maximum 320 VDC bus voltage. This product has no parts like brushes that tend to wear out over time. The device comes fitted with a PTC thermistor as well as a shaft seal that increases its lifespan. This unit’s exposed laminations also contribute to its high torque. Its AMP connectors for power and feedback are Mate-N-Lock connectors.
The motor’s speed reduces by 40% with one-phase line operation at 120 VAC. This product’s nominal stall current is based on its winding. The device supports a square key for its shaft. This unit’s connection is done with only the manufacturer’s cables for easy troubleshooting and best performance. It needs two cables for connection with the servo drive. The brushless servomotor has no brake to support the operation.
