Product Description:
The 4N63-100-1 Servo Motor is developed by Pacific Scientific. This specialized servomotor is created for different automotive applications in industrial automation systems. It has a rated voltage of 30 volts. Its continuous rated current is 6.8 amps RMS. It uses a low torque-constant winding for responsive motion control.
The 4N63-100-1 servo motor features a low inertia rotor of 0.0005 oz-in-sec² for fast acceleration. The rotor inertia is extremely low for agile dynamic response. The continuous current for a similar device variant is about 14.2 A at 42 V. Its continuous stall torque is round about 1.15 Nm. The Back-EMF constant is expected near 9.47 V/kRPM based on related variants. The thermal resistance is around 0.47 °C/W ensures proper heat dissipation. The terminal resistance was measured to be 0.89 ohms for efficient current flow. It includes air inlet and outlet cooling without internal baffles. The rotor inductance may be approximately 175 μH based on similar motors. The magnet material in the 4N63-100-1 servo motor is neodymium for a strong magnetic flux density. No analog tachometer is installed in the motor for speed feedback. The optical encoder is also absent, which simplifies the design. The Shaft diameter at the drive-end bearing is about 0.344 to 0.406 inches.
The cooling via airflow in 4N63-100-1 servo motor allows continuous duty without overheating. Its basic design lacks feedback devices but excels in rapid response. The environmental conditions typically include operating temperatures from 0 °C to 40 °C. The non-condensing humidity tolerance is generally up to 85 %. The vibration resistance often reaches 5 g RMS for industrial servo motors. The maximum altitude of the motor operation is up to 2000 meters above sea level. The environmental durability supports standard industrial temperature, humidity, vibration, and altitude conditions.
