The E32NCHA-LNN-NS-00 uses a hybrid stepper motor design, combining permanent magnet and variable reluctance technologies to achieve high torque density and precise step resolution. The motor features an octagonal housing design, which improves heat dissipation and allows for a more compact installation. The winding design is optimized for low loss and high efficiency, making it suitable for continuous-duty applications. The motor's high torque-to-inertia ratio allows for rapid acceleration, reducing cycle times in pick-and-place and assembly applications.
The motor can be used in open-loop mode with a standard stepper driver, or in closed-loop mode with an optional encoder (not included) to eliminate missed steps and improve positional accuracy. The "NS" in the model number indicates a standard shaft with no special modifications. The motor is compatible with Pacific Scientific's 6410 series stepper drives, as well as other industry-standard microstepping drives. The optional IP65 protection rating allows the motor to be used in dusty or wash-down environments.
This stepper motor is widely used in: CNC machinery (routers, mills, plasma cutters); packaging machinery (labelers, fillers, capping machines); pick-and-place robots and assembly automation; medical equipment (IV pumps, diagnostic instruments); textile machinery; and aerospace valve actuators. The NEMA 34 frame size provides high torque in a compact package, making it ideal for applications where space is limited but high holding torque is required.
