Product Description:
The PMB33C-00100-01 belongs to the PMB Brushless Servomotors series produced by Pacific Scientific. It is a three-phase permanent-magnet unit intended for closed-loop motion axes in automated packaging machines, pick-and-place gantries, and other positioning tasks that require repeatable torque and speed control. Within an electrical drive train, it converts drive current into rotary motion and returns resolver feedback to the controller so that the axis can be held precisely on its programmed profile.
The motor body follows the NEMA size 34 mounting pattern, allowing it to fit standardized U.S. frame hardware. A stack length multiple of 3 stator build increases the active iron length, giving higher continuous torque than shorter stacks that share the same frame. At 240 VAC, the phase winding draws a nominal stall current of 3.8 ARMS, which helps size amplifier current limits, cables, and protective devices. Rotor position and speed are measured with a Resolver, which is resistant to electrical noise and provides angle data for commutation. Field wiring is simplified because power and feedback conductors exit as flying leads with AMP connectors, so no separate terminal box is needed in tight cabinets.
A Flat shaft end transmits torque without keys and keeps coupling inertia low, which is beneficial when rapid acceleration is needed. To prevent lubricant migration or particle ingress, the unit is supplied with a Shaft Seal, making it suitable for lightly contaminated environments such as carton formers. The output arrangement also works well with clamp-style couplings that do not require a keyed shaft. The motor uses a modular brushless layout that supports integration with matching digital drives in closed-loop motion systems. This arrangement keeps the motor practical for compact servo axes where stable speed control and repeatable positioning are required.
