Oriental Motor 5GVR7.5B – KII Series Parallel Shaft Gearhead, 90 mm, 7.5:1, for 90 W Motors
The Oriental Motor 5GVR7.5B is a KII Series parallel shaft gearhead with a 7.5:1 gear ratio, a 90 mm (3.54 in) frame and a metric 18 mm output shaft. It is designed for Oriental Motor GVR-type pinion shaft motors in the 90 mm, 90 W class, such as the 5IK90GVR induction motors and the 5IK90UGVR speed control motors.
The 5GVR7.5B reduces motor speed by a factor of 7.5 and increases output torque. With the 90 W 5IK90GVR-UA induction motor at 115 VAC and 60 Hz, it gives a rated speed of 240 rpm and a rated torque of 3.9 N·m (34 lb-in). It suits conveyors, packaging machines and other general-purpose drives that need a moderate reduction from a higher-power motor.
