Product Description:

The PMB33F-00201-01 is a brushless servomotor manufactured by Pacific Scientific and supplied as part of the PMB Brushless Servomotors series. It is intended for closed-loop motion axes where accurate torque and speed response are needed for indexing tables, pick-and-place heads, and similar automation equipment. The rotor uses permanent magnets, so the motor can respond quickly to drive current while supporting precise position control with a matched controller. In automated systems, that behavior helps the axis follow programmed acceleration, dwell, and deceleration segments with consistent motion. The brushless design also avoids the wear associated with traditional brushed motor assemblies.

With a NEMA Size 34 frame, the housing follows the common 3.4-inch square mounting format used in many motion systems. The motor has a nominal stall current of 11.0 ARMS at 240 Vac, so the connected drive, cable sizing, and protection devices must support that locked-rotor demand. Commutation is supported by an integrated Hall sensor, which gives the controller the rotor-state information needed for startup and controlled low-speed rotation. The unit uses flying leads with MS connectors for power and feedback connections, which helps route cables in compact machine spaces while keeping terminations organized. Torque is transmitted through a flat shaft, which provides a simple coupling surface for hubs or clamp-style connections where space is limited.

An optional shaft seal helps protect the front bearing area from dust and light process contamination. This option is useful where lubricant mist, airborne debris, or general plant dust could shorten bearing life over time. A stack length multiple of 3 indicates the lamination length used for this motor build, and the added active length supports the torque output expected from this frame size. The unit is a PMB Series Brushless Servomotor, so it follows the electrical arrangement used across that product line. When used with a compatible controller from Pacific Scientific, it supports repeatable positioning and stable low-speed operation in industrial machinery.
