Product Description:
The PMB33C-20101-02 is an energy-efficient servo motor in the Pacific Scientific PMB series. Its flat shaft construction optimizes mechanical coupling by reducing backlash and enabling tighter alignment with driven components. This design ensures accurate torque delivery and minimal mechanical play by improving connection stability between the motor and load. The motor offers broad compatibility with PC800 and PC3400 series digital servo drives, ensuring seamless integration and optimal performance in a wide range of closed-loop motion control systems. This compatibility means that the motor’s electrical characteristics, such as winding impedance and feedback signaling, are precisely matched to the drive’s control algorithms. This results in accurate torque response, fast current regulation and stable motion profiles.
The PMB33C-20101-02 motor is equipped with PTC thermistors built into the windings, providing integrated thermal protection to safeguard the motor during operation. The thermistors increase their resistance as temperature rises, allowing control systems to detect overheating conditions in real time. This ensures that the motor can accurately monitor its internal temperature, enabling the drive or controller to take protective action before thermal damage occurs. This built-in safety mechanism extends the motor’s service life and enhances overall reliability in applications with continuous or high-duty cycles.
The PMB33C-20101-02 is built with high ruggedness, making it well-suited for demanding industrial environments. Its robust construction resists vibration, mechanical stress and external contaminants, ensuring consistent performance even under harsh operating conditions. This high level of ruggedness allows the motor to maintain precise motion control in applications with high cyclic loads or frequent start-stop operations. This motor comes in a NEMA 34 frame configuration, providing a sturdy and consistent platform capable of handling higher torque loads without compromising stability.
