Product Description:
The PMB33C-00200-02 Brushless Servo Motor uses neodymium iron boron magnets to deliver strong torque output. It is built with an 8 pole synchronous structure. The use of double shielded bearings in this model enhances reliability.
The PMB33C-00200-02 servo motor delivers excellent torque performance that is suitable for industrial applications. It features a continuous stall torque of 5.42 Nm that enables stable operation under sustained load conditions. The motor integrates a resolver sensor which provides high precision position feedback through absolute angular measurements and enhanced noise immunity. The motor provides a torque constant of 1.86 Nm/A (RMS) which defines the torque output per ampere of RMS current applied. The motor has a thermal time constant of 32 minutes which represents the time required for the motor’s winding temperature to reach approximately 63 % of the final steady state value after a step change in thermal load. This extended thermal time constant allows the motor to maintain stable performance under continuous duty operation. A Positive Temperature Coefficient (PTC) thermistor is integrated into the motor to provide precise and reliable thermal protection by increasing its resistance as the temperature rises. This feature prevents overheating and ensures safe and stable operation even during prolonged or continuous duty cycles.
The PMB33C-00200-02 servo motor from Pacific Scientific offers a peak torque of 16.1 Nm that provides high dynamic response for transient load demands. The motor also incorporates a flat shaft design that ensures secure torque transmission and reliable coupling with mating mechanical components. It requires a peak current of 8.7 A which represents the maximum instantaneous current needed to achieve rated peak performance. The industry standard mountings allow fast mechanical installation.
