Product Description

The role of automation devices is increasing in the manufacturing and other processes as they are capable of performing tasks accurately and at a higher speed than conventional devices. A lot of manufacturers thus are introducing automation devices but products of Pacific Scientist are preferred mostly due to their versatility and durability. The S21GNNA-RNNM-00 is one such brushless servo motor manufactured by Pacific Scientist which is known for providing maximum torque despite being lightweight and compact in size.

The feedback device features a primary resolver sensor for sensing the rotations of the machine and the hall sensor to sense and detect any changes in the speed, position, current, etc. of the machine which can affect the machining operation. The 6-pole servo motor features Neodymium magnets which provide high torque to inertia ratio which is best suited for industrial operations such as CNC machining, packaging, Laser cutting, etc. Pacific Scientists offers an MS connector with the brushless servo motor which increases the durability of the product.

The maximum rated speed offered by the S21GNNA-RNNM-00 is 12000RPM which is suitable for all above-mentioned machining operations. NEMA standards were followed while designing the frame of the motor which provides the user protection against current and also protects sensitive circuitry components from water, heat, dust particles, etc. which can damage the machine. The unsealed shaft of the S21GNNA-RNNM-00 is designed to be used in long working hours of the industry without being damaged. the S21GNNA-RNNM-00 only weighs about 1.6Kg and is compact in size which makes it easy to be used in low space areas. The brushless servo motor does not offer a holding brake so it can only be used in the applications requiring the horizontal configuration of the motor.
