Product Description:

This Pacific Scientific PMB33C-20214-02 synchronous servomotor has efficient heat dissipation. The motor is designed to support MS connectors. This product portrays peak torque for a maximum of five seconds. The device’s performance is reduced to approximately 85% when it operates with 240 VAC voltage and on a single phase. This unit has a rugged NEMA frame. It can be installed only in industrial machinery. The motor meets diverse automation requirements.

This product’s unique design is attributed to its exposed laminations. The device is protected against thermal overload by the integrated PTC thermistor. This unit houses a flat shaft for its operation. It has three rotor stacks. The motor houses 18-inch flying leads. This product encounters axial and radial forces when it is in its operational phase. The device’s windings are present in its stator. This unit’s permanent magnets in the rotor are made of a combination of neodymium, iron, and boron. Its mating connectors have to be bought separately.

The motor-related encoder is capable of performing commutation. This product’s installation in the vertical position is possible with the shaft upward or downward. The device’s hot surface shouldn’t be touched without using protective gloves, as it can cause burns. This unit’s flat shaft is fitted on its drive end. It must be taken care not to drop the motor during its transit. The synchronous servomotor’s brushless design makes it easy to service and repair. This product’s high torque density is achieved by the choice of material for its magnets. The device is to be used only with the appropriate servo drive from its manufacturer. This unit needs 10 cap-lead or fillister-lead screws for its mounting. It uses shielded cables for its connection.
