Product Description:

Danaher manufactures the SS451-1048 Synchronous Motor as a single-phase AC motor product used in industrial automation. Synchronous rotation in this motor provides constant speed operation even when experiencing mechanical loads. The motor rotates at 8.0 RPM at 60 Hz while it operates at 6.67 RPM when supplied with 50 Hz.

The SS451-1048 synchronous motor carries a CE certificate along with impedance protection features as part of its safety specifications. The motor relies on a standard flange mount to attach it to machinery. The motor consists of a metal structure that carries between 2.5 kg to 3.5 kg. Natural convection serves as the cooling mechanism because fans are unnecessary for this system. The SS451-1048 synchronous motorhas an insulation rating of Class B or Class F. While wiring construction follows the specifications in diagram reference 225006. This motor comes designed to operate as an indexing table device as well as a conveyor mechanism while providing positioning functionality. This motor functions well for repeated use when incidental and steady motion is needed. The motor has a 120 VAC rated voltage supply while drawing 0.8 Amps when in operation. This motor operates continuously without any experience of slippage during its operating motion.

The SS451-1048 synchronous motor arrives at customers without a preinstalled encoder. External feedback devices may be connected if required by the application. It is recommended for use in dry and clean indoor environments. The temperature specifications for this unit include operation between 0°C and 40°C. The motor does not specify any IP rating for dust or moisture. Operation of this motor occurs at low noise levels and causes minimal vibrations while in use. Single-phase input makes control system power connections easier to execute. The motor operates within light industrial fields where it provides constant speed control.
