Product Description:

The PMB33F-00214-03 is a brushless servomotor manufactured by Pacific Scientific and supplied within the PMB Brushless Servomotors series. This motor converts electrical power into controlled rotary motion for indexing tables, small gantry axes, and other industrial automation tasks that need accurate velocity and position control. Its encoder-based feedback allows the paired drive to regulate speed and position while also handling electronic commutation.

The frame follows the NEMA Size 34 standard, so it shares mounting dimensions with other size-34 actuators and can fit existing mechanical layouts. A nominal stall current of 11.0 ARMS at 240 VAC indicates the continuous current the drive must supply when the motor is locked but energized. Motion feedback is produced by a digital encoder that provides 2048 ppr, yielding precise incremental position information for the controller. The sensor is a Digital Encoder with commutation, allowing the drive to sequence phase currents without separate Hall devices. Power and feedback conductors exit as Flying leads with MS connectors, which simplify wiring because the leads are pre-terminated to military-style circular plugs.

The motor is shipped with a Shaft Seal and PTC Thermistor to help limit dust ingress and to signal winding overtemperature to the drive. The shaft end is machined with a Flat so couplings or pulleys can lock axially without added keys. Internally, the stack length is built to a multiple of 3, which increases the amount of active magnetic material for higher torque than shorter variants in the same frame. The PMB Series Brushless Servomotor configuration uses a resolverless encoder interface for compatibility with suitable Pacific Scientific drives.
