Product Description:
The PMB33C-00200-03 Servo Motor belongs to the PMB brushless servomotor family of Pacific Scientific. The motor is built for precise motion applications in industrial automation. It comes in a NEMA 34 frame size that follows standard mounting patterns. The motor uses flying leads with MS connectors for electrical interfacing.
The permanent magnets in PMB33C-00200-03 servo motor are constructed from neodymium iron boron material for strong magnetic fields. Its customization code 03 provides a shaft seal and PTC thermistor. These features protect against environmental exposure and help with thermal monitoring. The insulation system is rated as Class F to support higher thermal limits. The enclosure protection is specified as IP40, which makes it suitable for indoor use. This design ensures controlled operation in clean and dry industrial surroundings. The electrical parameters of the PMB33C-00200-03 servo motor match demanding servo applications. The C winding design carries a nominal stall current rating of 3.8 A. Continuous torque generation is approximately 5 Nm when operated with correct pairing. Peak torque values reach about 16 Nm for shorter duty cycles. Bus voltage supply includes 240 volts AC or 320 volts DC operation.
The speed values of the PMB33C-00200-03 servo motor depend on the connected drive and applied bus voltage. The no-load operating speeds reach up to 1900 rpm under rated supply. The feedback and mechanical features add to the operational performance of this servo motor. The resolver technology is especially useful for areas with electrical interference. The optional encoders are available with resolutions of 2048 PPR or 4096 PPR. The design also supports lower voltage operation within an 18 to 74 volt range. The standard sensing is performed by a resolver to provide an analog position feedback.
