Ingersoll Rand SM4AMB-A SM Series Direct Drive Vane Air Motor | Lube-Free | 1.5 HP | 7900 RPM | 2.6 (ft-lbs) Starting Torque | 4.1 (ft-lbs) Stall Torque

Ingersoll Rand SM4AMB-A SM Series Direct Drive Vane Air Motor is designed to provide reliable pneumatic rotary power for industrial equipment, machinery, and automation applications. This 1.5 HP lube-free air motor delivers a 7,900 RPM free speed, 2.6 lb-ft starting torque, and 4.1 lb-ft stall torque, providing responsive pneumatic power without traditional oil lubrication. The direct-drive vane design is well suited for applications requiring variable speed and torque, while vane assist supports low-pressure operation and quick starting and stopping.

The SM Series is designed as an alternative to electric motors where pneumatic power is preferred. The SM4AMB-A reaches maximum power at 3,000 RPM and has an air consumption of 67 SCFM at maximum power. This specific model is the Woodruff Key option, providing a defined shaft configuration for compatible equipment integration. The series also offers versatile mounting options, including foot, flange, hub, and NEMA configurations.

FAQs:

• Q: What does lube-free mean for the SM4AMB-A?
  A: The motor is designed to operate without traditional oil lubrication, making it suitable for applications where lubricant contamination or routine lubrication is undesirable.
• Q: What is the difference between free speed and speed at maximum power?
  A: Free speed is the motor's rotational speed without load, while speed at maximum power is the operating speed at which the motor produces its rated maximum power. For the SM4AMB-A, these values are 7,900 RPM and 3,000 RPM, respectively.
• Q: What does the Woodruff Key option indicate?
  A: The SM4AMB-A is identified by Ingersoll Rand as the Woodruff Key option. The shaft and mating equipment should be checked to ensure compatibility before installation.
• Q: What is vane assist?
  A: Vane assist is a feature of the SM Series that supports low-pressure operation and contributes to instant starting and stopping.
• Q: How much air does the SM4AMB-A consume?
  A: The published specification lists air consumption of 67 SCFM at maximum power.
• Q: Can this air motor replace an electric motor?
  A: The SM Series is designed as an alternative to electric motors. The motor's power, speed, torque, air requirements, shaft configuration, and mounting arrangement should be matched to the equipment before substitution.
