Product Description:

The SS451LE synchronous motor by Danaher functions by assisting the exact rotation of machines without speed variation even under load. Danaher focuses keenly on creating efficient products that help industries work more durably while consuming low energy.

The SS451LE synchronous motor works by featuring a 90 mm frame size suitable for fixed-speed and timing-sensitive applications. It operates as a single-phase unit which is compatible with standard 120 V AC power sources by making it practical for industrial automation and laboratory environments where a stable voltage supply is common. It consumes a current of 0.8 amps by allowing for consistent torque output. It is built to function at either 50 or 60 Hz and has rotational speeds of 60 RPM at 50 Hz and 72 RPM at 60 Hz. With a torque rating of 450 oz-in, it provides reliable mechanical force for various systems such as conveyors or actuators where exact shaft position and speed needs are critical. The impedance protection feature ensures that the windings are safeguarded from overcurrent conditions by adding to the unit’s operational reliability in domains where thermal or current fluctuations may occur and cause hazards.

The SS451LE synchronous motor’s design locks in with the power supply frequency which aids in eliminating velocity drift under varying loads. The unit also includes a standard wiring feature by referencing the specific configuration as PER225008 to support easy connection during installation. Housing components are enclosed and constructed to maintain performance in continuous or repetitive cycling operations. The labeling on the motor includes CE and UL Recognized (RU) marks which aids in confirming its stickiness with important safety and manufacturing standards applicable in regulated markets.
