Product Description:

The PMB22B-00114-00 belongs to the PMB Brushless Servomotors series produced by Pacific Scientific. It is a brushless servomotor intended for closed-loop positioning and speed control in industrial automation equipment such as pick-and-place gantries or compact indexers. By combining a permanent-magnet rotor with electronic commutation, the motor delivers repeatable torque and rapid reversal while maintaining precise alignment with feedback devices in the drive system.

This unit is built on a NEMA Size 23 frame, so its 2.25-inch square mounting face aligns with widely used stepper and servo brackets. The continuous thermal limit is set by a nominal stall current of 2.7 A RMS when supplied from a 240 V AC bus; the selected drive must remain within this value to avoid demagnetization. Position data are generated by an internal encoder that provides 2048 PPR of incremental resolution, allowing the controller to issue motion commands in sub-degree increments. Commutation and incremental tracks are contained in the same sensor package. The motor uses a digital encoder with commutation, which eliminates separate Hall devices and simplifies wiring. Power and feedback leave the housing through flying leads with AMP connectors, allowing the motor to connect to compatible harnesses without internal retermination.

The shaft is machined with a flat that provides positive engagement when clamped by a set-screw coupling, helping prevent slippage under bidirectional loads. The magnetic stack depth is twice that of the baseline model. This is represented by a stack length multiple of 2, which increases continuous torque without changing the mounting face dimensions. The configuration is a standard motor, meaning it does not include special seals, coatings, or windings. Its NEMA mounting face supports installation with common brackets, while the shaft flat provides a straightforward connection for compact couplings in positioning equipment.
