Product Description:

The Danaher SS400B synchronous motor from SLO-SYN utilizes SS400 B-grade hot-rolled steel for its structural components.

According to JIS G3101 standards, this material demonstrates ideal qualities for producing motor housings and support components due to its strong performance, combination of mechanical strength, ductility, and weldability. The steel in SS400B has a carbon composition of 0.14% to 0.22% with manganese quantities between 0.30% and 0.60%. Lower maximum phosphorus and sulfur amounts, at 0.035%, increase processing abilities and durability. The steel has specified minimum yield strength values set at 235 MPa and generates a wide range of tensile strength between 400 MPa and 510 MPa. The motor housing design utilizes SS400B steel to stay free of damage even under heavy mechanical handling and product use. It handles stress well during production and service since it stretches at least 20% without breaking. Due to its 200 GPa modulus of elasticity, it maintains precise geometric alignment and shape during motor assembly. It's material measures at 120 HB Brinell Hardness but still allows processing without harming the machine's structure.

This material type exhibits a typical steel density of 7.85 g/cm³ to deliver stable strength construction without excessive burden. The manufacturing process of the module makes its surface texture less smooth than cold-rolled steel, but this finish meets all the requirements needed for motor parts. The steel type SS400B takes shape as plates and structural components with excellent welding properties that help builders create strong structural connections easily. SS400B material selection in the synchronous motor shows designers chose robust and affordable steel that delivers dependable motion control results for industrial and commercial applications.
