Product Description:
This robust SRF3744-4266-7-56BC Permanent Magnet DC (PMDC) Motor is designed for high efficiency precision driven applications in industrial environments. This model features a durable cylindrical housing with a rugged blue coated finish. This motor incorporates a finely machined shaft supported by high-quality bearings to ensure smooth rotational motion and minimal mechanical wear.
The SRF3744-4266-7-56BC DC motor's rear end hosts a well ventilated cover that enhances airflow to maintain optimal operating temperatures and prolong the life of internal components. The electrical connections of this motor are securely housed within a metallic junction box. This box provides reliable protection against dust, moisture and mechanical impacts. It operates at 1800 RPM that makes it suitable for various machinery and automation systems. This motor includes permanent magnets that eliminates the need for external field excitation. This contributes to the motor’s compact size, high torque to weight ratio and efficient energy conversion. Its carbon brushes require periodic inspection to maintain consistent performance and prevent commutator damage. The recommended inspection interval is after 500 hours of use but it may vary depending on load and speed conditions. High speed and high current applications tend to accelerate brush wear while light load operations can also lead to increased wear on the brushes and commutator. Brush wear should not exceed 0.56 inches in length to avoid commutator damage.
The Kollmorgen SRF3744-4266-7-56BC DC motor provides steady torque output that is ideal for applications where precise speed control is needed. This DC Motor has a 1 HP power output and operated on a 90 VDC rated voltage. It offers low electrical noise and high quality internal components that allow it to function effectively in demanding industrial environments.
