Five different mounting configurations for both round and pear-shaped gearhead footprints gives the designer added flexibility in packaging the Synchron Model 148 permanent magnet DC motor/gearheads. In addition, 364 standard gear ratios are available ranging from 1.3:1 up to 6,000,000:1 with a maximum torque rating on most gearheads above 300:1 of 30 oz-in. This broad range of torque-speed characteristics adds greatly to the product matrix and provides the ease of choice desired by most engineers. For overload torque protection the gearheads may be selected with one-way or two-way slip clutches. The highly efficient DC motor has permanently lubricated sintered bearings and long life brushes and is 1.08 inches in diameter. Most motor/gearhead units are less than 2.0 inches long. Typical OEM applications would be printer ribbon drives, emergency flasher drives, and a variety of medical equipment and instrumentation drives. Various customizing features are available to OEM customers, such as special output shaft configurations, mounted pulleys or sprockets, terminal wiring and wire termination connectors.
