Product Description:
The Pacific Scientific designs PMB33C-00216-03 Servo motor for industrial automation operations. It is part of the PMB Series built with a NEMA Size 34 frame. It features a three-stack rotor length to offer a balance between physical dimensions and torque output. The winding configuration is identified by the C designation.
The PMB33C-00216-03 servo motor incorporates a PTC thermistor for temperature monitoring. This provides active thermal protection during operation. The current demand at continuous stall torque is 2.7 amperes RMS. It increases to 5.3 A RMS at peak torque output. The position and velocity data are provided by a digital encoder with commutation capability. The encoder resolution is 4096 pulses per revolution to enable precise motion regulation. The motor has a rated rotational speed of 1300 RPM, with a no-load speed of 1900 RPM. The electrical connections of the PMB33C-00216-03 servo motor are implemented using flying leads with AMP-style terminations. It allows flexible cable routing while ensuring secure connections. The output shaft of the servo motor is 26 mm. This makes it compatible with specific mechanical coupling systems. The peak stall torque and peak rated torque are both 9.7 Nm. The continuous stall torque is rated at 5.0 Nm. The continuous rated torque of the PMB servo motor is 4.8 Nm. The rotor has a mass moment of inertia of 0.40 × 10⁻³ kg·m².
The PMB33C-00216-03 Servo motor operates on a 240-volt AC input and is also compatible with a 320-volt DC supply. Winding inductance is specified at 27.2 mH line-to-line, which influences current regulation characteristics. The motor has an IP40 enclosure, which gives it basic protection against solid objects but does not make it dust-tight or water-resistant. The construction of the motor uses quality bearings and strong magnets, which add durability.
