Product Description:
The SS150B synchronous motor is manufactured by Danaher and belongs to the Slo-Syn Synchronous Motors series. As a constant-speed AC drive, it is used in industrial automation to index packaging lines, actuate conveyors, or position process valves without closed-loop feedback. By locking its rotor magnetically to the line frequency, the unit delivers repeatable motion when connected to a timing chain or gear train.
Electrical operation is straightforward because the motor is rated for 120 VAC mains power at 60 Hz. At this supply voltage, it draws 0.45 A, a modest current that simplifies branch-circuit protection. It has a single-phase design, so a phase-shift network is required; Danaher specifies a 3.75 µF run capacitor in series with a 250 Ω starting resistor. The resistor must be rated to dissipate 25 W, keeping its temperature rise within safe limits during startup. These components establish the auxiliary winding’s quadrature field, allowing the stator to pull the rotor into synchronism without external electronics. Once synchronized, power consumption stabilizes, and the motor can remain stalled against a load without overheating, a useful characteristic in intermittent-motion machinery.
Mechanical performance supports moderate loads. The motor produces a minimum running torque of 150 oz-in (1.06 Nm) while maintaining a synchronous speed of 72 rpm, so indexing tables receive steady angular increments even when friction varies. Its total weight is 8.0 lb, making it practical for direct mounting on light frames. The bearing set can absorb up to 50 lb of axial thrust and 25 lb of radial side load. The allowable load inertia is 0.062 oz-in-s², which keeps acceleration within the available torque range. A 3.000-inch bolt circle and a 2.186-inch pilot diameter center the housing, while the 4.74-inch overall length allows installation inside compact enclosures.
