Oriental Motor Introduces the PV Series Stepping Motor
Oriental Motor USA Corp. (Japan) introduced the PV Series high-torque, two-phase, hybrid stepping motor. Using advanced design techniques, the PV Series produces at least 25 percent more torque than other two-phase stepping motors of the same size, giving it the highest torque density of any two-phase stepping motor, according to the company.
Oriental claims that the new PV Series is also more energy efficient and provides better position accuracy. The step angle accuracy has been improved by 50 percent to a static angular error of + 0.033 arc degrees (2.0 arc-minutes). In addition, vibration has been greatly reduced, with resulting audible noise being reduced by an average of 8dbA from 200rpm to 1,500rpm.
The PV Series includes 32 new models. The smallest models are the PV264 types (2.36in x 1.71in). The PV264-02AA produces up to 106 oz-in of holding torque with 2A per phase of input current. At 48Vdc input, the PV264-D2.88AA has a pull-out torque of 77 oz-in at 1,000rpm.
The largest model in the PV Series is the PV269 type (2.36in x 3.35in). The PV269-02AA achieves a holding torque of 440 oz-in with 2.8A per phase of input current. At 48Vdc input, the PV269-D2.88AA has a pull-out torque of 183 oz-in at 500rpm.
