Product Description:
The SRF3744-4266-84-5-56HC DC Motor is designed for reliable and efficient performance. It is manufactured with precision to support various industrial automation applications. Its robust construction ensures durability under demanding conditions. This motor is suitable for equipment requiring consistent power and operational stability.
This SRF3744-4266-84-5-56HC DC motor operates at 90 V DC with an amperage of 9.3. It provides 1 horsepower for optimal output. It delivers a rotational speed of 1750 RPM that ensures smooth mechanical performance. This motor features a brush and commutator system that requires regular inspection after 500 hours of use to maintain efficiency. Brush length should not fall below 0.56 inches, with a new brush length of 1.03 inches. High speed or high current operations can increase brush wear that necessitates preventive maintenance. This motor should be operated exclusively with the accessories specified and recommended by the manufacturer (Kollmorgen). This includes but is not limited to compatible controllers, drives, cables, connectors and mounting hardware. Troubleshooting common issues like non operation may involve checking for worn brushes, loose power leads or an open armature. Corrective actions include replacing brushes, tightening leads or repairing the armature. If the motor runs in the wrong direction, verifying and correcting lead polarity resolves the issue.
The SRF3744-4266-84-5-56HC DC motor’s design supports both high load and light load conditions. Brush and commutator wear may occur faster under light load operations. Regular maintenance helps prevent damage with recommended inspections to track brush length reduction. The motor’s construction supports efficient heat dissipation and operational longevity. Its stable performance across various speeds and loads makes it versatile for multiple industrial applications. This motor ensures dependable performance through meticulous engineering and proper maintenance protocols.
