The Model 750 DC Tachometer-Generator embodies a permanent magnet field surrounding a rotating armature. The commutator segments are made from a special non-corrosive alloy which has an exceptionally long life. The brushes are of a self-lubricating material and are carried in a self-aligning holder which equalizes the pressure of both brushes. The armature shaft rotates on ball bearings which under normal operation do not need lubrication for 15,000 hours running time or approximately 3 years, whichever comes first. Maximum recommended speed is 5,000 rpm. Brush life is greatest at the lower speeds.
Approximate torque: 1.0 oz.-in. starting, 1.0 oz.-in. running (1000 RPM).
- Linear voltage output based on RPM
- Dust-proof aluminum housing and Mounting base.
- 3/8" diameter shaft extension for direct coupling drive, pulley, spur gear, or chain and sprocket.
- Two binding posts for electrical connection.
