Product Description:

The PMB33F-00214-01 is a brushless servomotor built by Pacific Scientific, and it belongs to the PMB Brushless Servomotors series. Intended for closed-loop industrial drives, the motor converts electrical energy into controlled rotary motion for positioning tables, pick-and-place arms, and other automated axes. Integrated electronic feedback lets the drive synchronize rotor angle with command signals, so this servomotor functions as the mechanical workhorse inside compact motion modules where fast acceleration and repeatable accuracy are required.

Electrical and feedback characteristics affect how the unit interfaces with a drive. The frame is specified as NEMA size 34, giving a square mounting face suitable for mid-torque applications while keeping the motor envelope under 3.4 inches. During stall at 240 VAC, the windings can carry 11.0 ARMS, a current ceiling that dictates drive amplifier sizing and thermal limits. Position data comes from an integral encoder producing 2048 ppr, and this resolution is paired with a digital encoder with commutation so the controller receives both incremental counts and phase information for sinusoidal current control. Field wiring is simplified by flying leads with MS connectors, allowing the motor to be installed without soldering or crimping separate plug assemblies.

Mechanical features adapt the motor to the target machine. A flat shaft end provides a firm contact surface for set-screw couplings, eliminating the need for an external keyway. Magnetic output is increased by a stack length multiple of 3, which adds laminations to raise continuous torque without changing the frontal footprint. A shaft seal helps limit the entry of coolant mist or fine dust. These options support different duty cycles while keeping the motor compatible with compact machine layouts.
