Product Description:
The S21HNNA-HGNS-02 is an industrial motor built by Pacific Scientific to provide production and processing machines with a well-controlled torque supply. This motor is built to meet international quality standards and has been certified for use in North America, Europe and Asia. The handling and installation of this motor unit is relatively straightforward due to its small housing size and design. As a permanent magnet excited motor, special neodymium-iron-boron magnets are installed on the shaft of this motor unit. These unique magnetic material allows the motor to maintain an impressively low inertial level throughout its operation. The S21HNNA-HGNS-02 motor unit maintains a continuous stall torque of about 0.5 newton meters during operation, and it also has a total weight of approximately 1.4 kilograms. The NEMA frame size of this industrial motor unit is NEMA 23, and its peak torque output is also about 1.36 newton meters.
The S21HNNA-HGNS-02 industrial motor operates with a Hall Sensor as its primary feedback device; it also features another sensor which functions as its secondary feedback unit. The torque produced in this industrial motor is transmitted to output torques through a strong shaft that is able to support relatively high loads. This integrated shaft is without a shaft sealing ring. There is no holding brake attached to this industrial motor unit.
Compared to other motors of similar size, the S21HNNA-HGNS-02 produces significantly high torque while consuming lower current. The thermal time constant for this motor is about 5 minutes, and its thermal resistance is also estimated to be about 2.2 degrees Celsius per watt. The typical rated speed of this brushless motor during operation is estimated to be as high as 12,500 revolutions per minute. Its current consumption at peak torque is about 9.3 amperes.
