Product Description:
The PMB33E-00101-02 is a brushless servo motor produced by Pacific Scientific and supplied within the PMB Brushless Servomotors series. It converts electrical power into controlled rotary motion for indexing tables, pick-and-place heads, and other closed-loop axes used in automated equipment. Integrated rotor magnets and electronic commutation support accurate speed and position response without brush wear, which helps reduce particle generation and routine service needs. In a servo system, the motor can respond quickly to command changes during starts, stops, and reversals. The motor is well suited for packaging, assembly, and semiconductor systems that require repeatable motion in a compact drive package.
The frame follows the NEMA Size 34 standard, so its mounting face and pilot diameter fit widely used 3.4-inch motor brackets. The stator windings can draw up to 7.4 ARMS of stall current when operated from a 240 VAC drive bus, giving the amplifier the current needed for low-speed torque production. Power leaves the housing through flying leads with AMP connectors, which allows direct connection to matching harnesses without a separate terminal box. This arrangement keeps external wiring simple when the motor is installed on moving axes or compact machine slides. Rotor position feedback is provided by an internal Hall sensor, and those signals support commutation during startup and low-speed operation.
Thermal monitoring is provided by a PTC thermistor embedded in the stator, so its resistance rises with temperature and the drive can react before overheating occurs. This type of protection is useful during repetitive indexing or dwell cycles that build heat in the windings. The motor uses a flat shaft end, which gives clamp-style and setscrew couplings a consistent contact surface for secure torque transfer. The electromagnetic core uses a stack length multiple of 3, increasing active material length without changing the mounting face. That longer magnetic stack helps raise available torque in the same frame and supports compact machine layouts where space for a larger motor is limited.
