Product Description:
The S21HSNA-RNNM-04 is a precision industrial motor with high-speed capabilities. It is part of the Pacific Scientific range of brushless motors designed for low-maintenance operation and long service life. Its precision design enables highly accurate motion control, which is essential in systems requiring exact positioning and finely-regulated speed. This motor features a single stack construction that ensures a balanced trade-off between torque output and compactness. With only one magnetic stack, the motor maintains a smaller footprint and lower weight, making it ideal for systems requiring multiple axes of motion.
The S21HSNA-RNNM-04 is engineered to deliver a maximum speed of 12,500 RPM, making it well-suited for high-speed industrial tasks. The motor can efficiently drive machinery that requires quick repositioning or high-frequency movement, such as in automated pick-and-place systems or high-speed spindles. Its enhanced speed capabilities contribute to reduced cycle times, enhancing overall system productivity. This unit offers a flexible +4.5 to +24 VDC range of input, enabling compatibility with both low-voltage logic circuits and higher-voltage industrial controllers. This enhances system design and ensures that minor fluctuations in power supply do not impact performance reliability.
This motor has a continuous current rating of 3.8 A, enabling minimal power draw while still supporting consistent performance. The motor is optimized for precision performance with integrated motor feedback that is facilitated by a robust resolver. The resolver uses analog signals to provide continuous and absolute position data, enhancing performance accuracy over long operating periods. This motor comes with winding type H, which is optimized for high-speed and high-voltage industrial applications. This winding configuration supports efficient thermal performance and minimizes electrical losses, allowing the motor to sustain higher speeds, ensuring consistent output under demanding operating conditions.
