Product Description:

The model SR3640-8293-7-48C is a Permanent Magnet (PMDC) DC Motor designed for demanding industrial applications. This motor ensures efficient performance and long service life. It operates at 1800 RPM that is suitable for various motion control and automation systems.

This SR3640-8293-7-48C DC motor has a 4.7 A current rating that ensures stable operation under varying loads. The rugged fused commutator in the DC motor enhances durability and provides reliable electrical contact. It is equipped with large sealed bearings which improve mechanical stability and reduce maintenance needs. The H class insulation allows this motor to withstand high temperatures. This ensures safety and longevity in continuous operations. This motor’s exterior may reach high temperatures during operation that requires caution when handling. Proper installation following local and national electrical safety codes is essential for safe use. To maintain optimal performance, silicone vapors should be avoided as exposure to RTV, oils, mold release agents and varnishes can accelerate brush wear. This PMDC motor is designed for industrial environments requiring precision, efficiency and durability. Regular inspection and maintenance will help sustain performance over time.

This Kollmorgen SR3640-8293-7-48C DC motor is engineered with patented anti cogging magnet technology. This technology ensures exceptionally smooth and precise performance even at low speeds. This feature eliminates the jerky motion commonly associated with traditional motors. This motor incorporates a high quality polyester impregnated armature which enhances both electrical and mechanical integrity. This design not only improves durability and resistance to wear but also ensures optimal electrical conductivity. This also reduces energy loss and improving overall efficiency. The robust construction of the armature further contributes to this DC motor's ability to withstand demanding operating conditions.
