Product Description

The M21NRXC-LSS-NS-03 POWERMAX II brand hybrid stepper motor from Pacific Scientific makes use of SIGMAX technology for its operation. The enhanced type motor has a large shaft diameter that makes it capable of withstanding high axial and radial loads. It has a NEMA 23 size that represents a size of 2.25 inches across flats. The two-phase product covers 200 full steps for each revolution. It features high-performance gearheads. The optimally designed device comprises high-quality magnets, high temperature insulation and long-life bearings. The unit encompasses samarium cobalt magnets in the stator teeth. These magnets concentrate the magnetic flux at preferred points between the rotor and stator.

The hybrid motor bearings feature a fatigue life of more than 10,000 hours if operated within the maximum permissible radial and axial loads. The device has a winding resistance of 1.56 Ohms. The polymer encapsulation on the stator and lamination on the rotor render enhanced thermal dissipation. This product has a standard winding type of C. The SIGMAX technology helps in increasing the torque already available. The polymer end bell is fitted with threaded inserts and operates a cooler. The high-quality unit offers the assurance of a dependable operation every time it is used.

The stepper motor comes with a special shaft configuration with special shaft modification. The regular construction style product also features a single stack, NEMA type mounting and receptacle type termination. The mating leaded connectors for this device can be ordered separately. The unit has a sequence number of 03. It does not incorporate any encoder as there is no feedback. The device has a rated current of 3.1A per winding, a dielectric voltage rating of 500VDC and a step angle of 1.8°C. The motor can be shipped to any address, with a warranty of one year.
