Synchron PM Rotor Step Motor

The new Synchron tin-can step motor uses a permanent magnet (PM) rotor to provide up to 9.0 oz-in of holding torque in a compact, precision power package of 1.9 inch diameter by 1.0 inch length. The basic step sizes are 7.5 degree (48 steps/rev)and 15 degree (24 steps/rev). Either the four-phase, eight lead-wire stator or the two-phase, four lead-wire stator provide the flexibility to be driven from L/R drivers in either full step or half-step modes. The standard voltages are 5VDC, 12VDC or 24VDC; other voltages are available. Class A (105 degree C) windings are standard, but class F (155 degree C) are optionally available to cover a wide range of operating temperatures. The low inertia rotor provides for high acceleration characteristics and the low mechanical time constant provides a capablility for rapid start-stop applications. Mechanically these OEM-economical step motors are adaptable for either sleeve, roller or ball bearings depending upon the application loading and mount with a two-hole faceplate. Optional matched gearheads are available to increase step resolution, increase torque and reduce speed. The step motors find application in both commercial and industrial timing equipment and in axis positioning instrumentation.
