Product Description:

Pacific Scientific produces the PMB31D-10100-03 brushless servomotor, and it can handle applications that require precise control due to its NEMA Size 34 frame construction. The motor has a spherical shaft and a resolver sensor. For applications requiring consistent torque and motor feedback, the PMB31D is an ideal choice in industrial automation systems.

The PMB31D-10100-03 brushless servo motor is the ideal choice for industrial automation systems that require precision and dependability. Both the rated and stall torques peak at 6.2 Nm. The maximum torque requires 15.3 amps of RMS current. Its winding may operate at a maximum voltage of 240 V AC. The nominal and continuous stall currents are 5.4 and 5.1 amps RMS, respectively. The PMB31D servo motor includes flying leads with AMP connections for convenient hookup. The resolver sensor type and spherical shaft structure allow for precise rotor location detection. The motor includes a PTC thermistor for safety and a customization code that identifies a shaft seal given by the manufacturer. These features align the motor with control requirements such as precision, safeguarding, and torque adjustment.

The PMB31D-10100-03 brushless servo motor includes both a resolver sensor and a shaft seal. These components offer internal protection and continual signal feedback. Without a load, the motor can reach 8400 rpm, but its rated speed is 5000 rpm. It is possible to keep a steady stall torque of 2.1 Nm and a rated torque of 1.7 Nm. The motor's design suits automated systems that need continuous torque and exact feedback. To prevent thermal overload, the design incorporates a PTC thermistor to monitor the temperatures of the windings. The brushless servo motor is designed with the system's requirements for consistent speed and signal accuracy.
