Product Description:

The PMB33E-20216-00 belongs to the PMB Brushless Servomotors series manufactured by Pacific Scientific. It is a three-phase permanent-magnet servo motor intended for closed-loop positioning and velocity control on automated axes such as gantry slides, pick-and-place heads, and indexing tables. When paired with a compatible drive, the motor converts commanded current into controlled torque so that machine motion follows digital trajectories with stable response and repeatable movement. Its brushless design also supports continuous cyclic operation in equipment that depends on accurate speed and position feedback.

When operated from a 240 VAC drive supply, the motor has a nominal stall current of 7.4 ARMS, allowing mid-range drives to deliver full static torque without overload. The housing uses a NEMA Size 34 flange standard, which provides a 3.4-inch square face for common industrial mounting patterns. Rotor position feedback comes from an optical encoder with 4096 ppr resolution, giving incremental data that supports stable speed control and accurate position updates. Power, signal, and earth conductors terminate as Flying leads with MS connectors, which allows connection to matching harnesses or panel interfaces. This arrangement keeps the electrical interface straightforward while preserving separate paths for motor power and feedback wiring.

The output shaft uses a Square Key cut, so couplings and pulleys can transmit torque without depending only on clamping force. The motor is built as a Standard Motor, which indicates a standard configuration rather than a special finish or sealing option. A stack length multiplier of 3 gives the motor a longer active section than shorter units in the same frame size. Feedback is provided by a Digital Encoder with commutation, so the drive receives position counts and commutation signals from one device during startup and low-speed operation.
