Product Description:

The PMB33E-00201-00 is a brushless servomotor produced by Pacific Scientific and supplied within the PMB Brushless Servomotors series. Designed for servo loops that demand precise speed and position control, the unit couples directly to gearing or loads to deliver smooth, digitally commanded motion. In automated equipment, it fills the role of the primary mechanical actuator, responding to drive commands with low inertia and accurate feedback for repeatable production cycles. Its brushless design also supports consistent torque delivery during repeated indexing and other closed-loop motion tasks.

With its NEMA Size 34 frame, the motor follows a 3.38-inch square mounting pattern, so it fits common machinery brackets without adaptation. The motor draws a nominal current of 7.4 ARMS at continuous stall, allowing the companion drive to size its power stage and protective devices correctly. Electrical terminations exit the housing as flying leads with MS connectors, allowing direct connection to a cabinet harness. Rotor position is detected by an integrated Hall sensor, giving the drive three-phase commutation signals without requiring an encoder for commutation. Mechanical power is delivered through a flat shaft, which provides repeatable coupling alignment and helps prevent rotational slip at the hub. This combination of frame size, terminations, and shaft style supports compact integration into packaged motion assemblies.

The torque capability comes from a stack length multiple of 3, meaning three lamination stacks are used to increase magnetic flux and raise continuous output beyond shorter motors in the line. Because it is classified as a standard motor, the unit uses the base insulation, bearing set, and lubrication intended for general operating conditions. The motor is a PMB Series Brushless Servomotor, and its electrical constants match the control approach used across the product line. The dimensional format used by Pacific Scientific keeps the mounting envelope consistent with the PMB platform.
