Product Description:

The 4N63-100-2 is of high torque motor. It is created to give accurate power in small systems needing the right torque and response speed. Powered at 48 volts, the motor delivers a rated torque of 1.15 Nm, consistent rotational force under any condition.

Power rating is 404 watts, suitable for systems requiring efficient performance without excessive energy consumption. The motor is capable of a maximum pulse current of 47 amps, with enough power to manage high-demand bursts, facilitating quick acceleration or torque increase without sacrificing structure. Rotor inertia is 6.3 x 10⁻⁶ kg·m², to facilitate rapid direction change and smooth speed transition, as critical where rapid response is necessary. A 0.090 Nm/A torque constant gives better torque proportionality with applied current. It ensures control and keeps calibration easy. Such linearity is useful for servo tasks and load sensitive operations. The 9.47 V/kRPM back EMF constant gives good speed control. It improves integrity of motor feedback. This gives synchronization help in multi-axis operations. Rotor inductance in this unit is 175 μH. It is used to help damp high-frequency current spikes. This prevents the risk of electromagnetic interference with sensitive devices. The motor is suitable for systems wherein stable, consistent power is a requirement, for example, in robotics, medical systems, or compact manufacturing systems. Its compact design makes it easy to fit into space-restricted assemblies without trading off on torque and power. The motor design allows for efficient thermal management, offering continuous use under stressful cycles without overheating. With low friction and well-balanced electrical features, it offers repeatable performance with minimal maintenance.

Engineered for smooth control and accurate movement, the 4N63-100-2 offers a reliable alternative where stability, responsiveness, and efficient energy usage is a necessity. It's an ideal piece of equipment for engineered applications requiring smooth torque and speed coordination with minimal overshoot and no lag.
