FAQs:
- Q: Is the 7801-3B reversible?
A: No. The 7801-3B is a non-reversible milling motor designed for forward rotation. - Q: What does single gear reduction mean?
A: It means the motor incorporates a single gear-reduction stage to provide a reduced output speed compared with the motor's input speed. - Q: What is the free speed of the 7801-3B?
A: The published free speed is 4,600 RPM. - Q: What does the 4.00 ft-lbs stall torque rating indicate?
A: Stall torque is the torque available when the motor is stopped under load. The 7801-3B has a published stall torque of 4.00 ft-lbs. - Q: What type of equipment can use this milling motor?
A: It is intended for compatible milling machinery and other equipment requiring forward-only pneumatic rotary power. The motor's speed, torque, mounting, and drive requirements should be matched to the equipment before installation.
