S33ANNH-RNNM-00 Image 1


The S33ANNH-RNNM-00 is a high-performance servomotor in the S Motor Series by Pacific Scientific. Specifically, it falls under the S33 series, characterized by a frame size of 33 and the compatibility with both NEMA or metric mounting. The S33ANNH-RNNM-00 is known for its compatibility with the PC8x3 and SCE9x3 drive systems, both featuring a high torque rating. This particular motor utilizes 6-pole Neodymium magnets which enhance the motor's resistance to demagnetization. It also exhibits a torque constant of 1.5Nm/Arms and a voltage constant of 98.4 Vrms/kRPM, coupled by two types of voltage buses – a 240Vdc, 320Vac bus with a typical rated torque of 4.7Nm, and a 400Vdc, 560Vac bus with a rated torque of 4.0Nm. Moreover, the S33ANNH-RNNM-00 servomotor is relatively light, weighing only 6.5kg, and incorporates a peak torque of 15.3Nm. It's equipped with low-rotor inertia offering excellent acceleration and deceleration capabilities, thus eliminating the need for an optional holding brake. This servomotor features a frameless primary feedback resolver of size 21, with the option for secondary feedback. Connections are robust and seamless, secured via a motor-mounted MS connector. Offering sufficient protection features such as TENV construction, H-class insulation, and an over-temperature thermistor, this servomotor promises durability and reliability.

S33ANNH-RNNM-00 by Pacific Scientific is a Brushless Servo Motor in the S Series. The S33ANNH-RNNM-00 features a Frame Size/Stack Length of NEMA 34/3 Stack and a Holding Brake Option of No Brake. This Brushless Servo Motor also has a Size 21 Frameless Resolver for Primary Feedback and a Secondary Feedback of No Secondary. Additional specifications include a NEMA Frame for Shaft & Mounting and a Motor mounted MS Connector for Terminations.
