One model under the E33 series motors is the E33NRHB-LDN-NS-00, where the letter E stands for the series (Sigma-x) NEMA 34 frame set of motors with a three-stack rotor or number of rotors that can even vary. This motor is framed with heavy-duty front-end bell and shaft, and sealed system rear end bell with MS connectors. It also has a bipolar parallel connection, a maximum torque at high-speed winding, a straight keyway, encoder mounting provisions, and a shaft seal.
Different modifications of the given motor are given and required model indicates the use of the motor, usually in the industry related to the motion systems or other related works. Pacific Scientific has designed motors with different modifications for specific usage in the above-mentioned industries. The E33 series provides a wide range of motion systems and control of mechanisms. There are different configurations available for the given model of the motor, in this case, the E33NRHB-LDN-NS-00.
To start with, the E indicates the sigma-x basic series of motor standards. The very first digit 3 indicates the size of the motor, 3 indicates NEMA 34 in inches, while the number of Rotor Stacks are also 3. The next letter shows the mounting configuration and combination as N indicates NEMA (n/a 4 Stacks). The R represents the Regular and Lead-wire type construction of wires. Windings per lead are 4 in parallel form. Here, B shows the additional standard of winding type for the given model of the motor. L represents the Laminated rotor type and the DN shows double shaft configuration and smooth mounting configuration of the shaft. The NS represents that no Feedback is provided. Standard motor with no seal is used which is given by 00.
