Product Description:

For complex automation tasks, its precision and dependability in motion delivery are ideal. The M22NLSB-JDS-NS-02 motor is a high-performance motion control solution designed by Pacific Scientific. To maximize performance, its design incorporates a low-inertia design that boosts acceleration and deceleration rates.

The M22NLSB-JDS-NS-02 motor's efficiency is enhanced by its B-type winding and specific connection layout. The low inertia design of the rotor type J allows for quick dynamic responses. A strong holding capability is provided by the motor's holding torque that is 237 oz-in (1.67 Nm). The motor guarantees efficient current regulation with a phase resistance of 4.98 ohms. Two stacks on the M22 motor allow for increased torque output while also lowering the unit's footprint. Because it is mounted using the NEMA type, the motor can be easily incorporated into systems that are already in motion. Because of its thermal resistance value of 4.5 degrees Celsius per watt, the motor is able to effectively remove heat even when it is performing continuous operation. Rotor inertia of 0.0026 oz-in² (0.018 kg·m² × 10⁻³) is suitable for applications requiring high speeds and rapid start-stop cycles.

To further improve its mechanical stability under load situations, the motor can withstand axial shaft loadings up to 13 lb (58 N). The motor's 2-frame size is in accordance with NEMA 23 regulations that makes it compatible with a broad variety of applications. The motor design has an emphasis on low inertia in order to additionally improve the responsiveness of motion sequences. For industrial automation tasks that demand absolute accuracy and dependability, the M22NLSB-JDS-NS-02 motor is an excellent choice. Because of its reliable design, it is an essential part of motion control systems.
