Product Description
The M21NRXD-LSS-M1-02 hybrid stepper motor has a honed stator ID and a precision-ground rotor ID. This Pacific Scientific motor has a D type of standard winding and regular construction style. It is equipped with a provision for mounting an encoder. The product features a laminated one-stack rotor. The mating connector has a high retention force because of the integral electrical receptacle. The device encompasses a molded stator assembly. The unit supports NEMA type mounting. The bearings have four times the lifespan of those in standard NEMA 23 motors. The lamination in the rotor offers the assurance of high efficiency. The stepper motor comes with a one-year warranty period.
The motor encapsulates a concentric air gap in an economical design. The large size of the bearings helps to reduce the downtime of the device. Green/yellow ground wires are optionally available for this unit. The device features Class B insulation at 130°C. The unit has a protection class of IP 23 and a full step angle of 1.8°. It supports a maximum radial load of 20lbs. in the middle of the standard shaft extension. The product has a sequence number of 02. The device has an overall length of 78.8mm and is equipped with two phases.
The laminated rotor is integrated with rare earth neodymium-iron-boron magnets. The exposed lamination helps in thermal dissipation. The octagonal shape contributes to the simplification of the automated assembly. The bearings have a size of 30 mm. The fatigue life of the bearings is 400% more than that of standard 20mm bearings. The M21NRXD-LSS-M1-02 device also has an extended life because of enhanced heat dissipation. Its stator features a polymer encapsulation. The motor operates between an ambient temperature range of -20°C and +40°C. It can be safely dispatched to your address through our regular freight forwarders.
