With a Frame Size of 56C and a compact profile, it integrates seamlessly into existing drive systems while minimizing footprint. The motor’s construction emphasizes endurance: it features Class H insulation to resist thermal stress and maintain winding integrity under prolonged load. Designed for demanding applications, the BA3648-4683-9-56C balances power density with operational longevity, reflecting Pacific Scientific’s commitment to high-quality motion control solutions.

The BA3648-4683-9-56C permanent magnet DC motor exhibits a series of critical specifications that define its electrical and mechanical capabilities. It operates at 140 VDC voltage, drawing 5 A current under full load, and generates 0.75 HP (3/4 HP) continuous output. The motor delivers a nominal 1750 RPM rated speed while maintaining a constant torque profile throughout its duty cycle. Encapsulated within a 56C frame, the enclosure rating is designated as Watts 4 to indicate environmental protection level. Insulation is certified as Class H, enabling a Maximum Case Temperature of 135°C without compromising dielectric strength. Designed for Continuous (CONT) duty, the motor tolerates ambient temperatures up to 40°C. Classified as a DC Motor, this unit combines permanent magnet excitation with precision winding techniques to optimize efficiency and minimize ripple.

Operational features of the BA3648-4683-9-56C emphasize reliability and consistent performance in industrial settings. Continuous-duty operation ensures the motor can run uninterrupted at rated load, eliminating the need for frequent thermal cooldowns. The high-temperature resilience provided by Class H insulation and a 135°C maximum case temperature rating protects internal components during extended runs and peak torque demands. The motor’s permanent magnet design reduces maintenance requirements by eliminating brushes and commutators, enhancing service life. Low electrical noise and predictable speed regulation at 1750 RPM make it ideal for applications requiring smooth acceleration and deceleration profiles. Enclosure protection further guards against particulate ingress, ensuring stable performance in dusty or humid environments.

The BA3648-4683-9-56C integrates readily with standard industrial drive controllers and motor management systems, supporting pulse-width modulation and analog control schemes. Its 56C frame size and standardized mounting interfaces simplify retrofitting into conveyor drives, rotary indexing tables, and precision positioning systems. Targeted applications include factory automation, packaging machinery, material handling, and laboratory instrumentation where consistent torque delivery and compact design are critical. Pacific Scientific’s global support network ensures streamlined commissioning, calibration, and lifecycle maintenance for seamless system integration and industry-compliant performance.
