Product Description:
The Pacific Scientific's PMB33C-00201-02 motor has an IP40 type construction that provides a controlled environment fit without compromising structural integrity. For conditions in diverse altitudes, this motor is designed for installation up to 1000 meters above sea level, ensuring performance robustness at high elevations.
This motor uses neodymium-iron-boron magnets, which are characterized by excellent magnetic performance, to provide stable torque during high-demand operations. This servo motor provides a rated torque of 4.83 Nm, providing consistent performance during constant operations. To facilitate heavy-load, short-time applications, this motor provides a peak torque capability of 16.1 Nm for motion control flexibility. Supporting this performance, this motor consumes a current of 8.7 Arms under peak torque to ensure that it can accommodate transient load spikes without affecting system stability. The rated stall current of the PMB33C-00201-02 brushless servo motor is 3.8 Arms, which is the current needed to hold rated torque at zero speed without excessive heat in intermittent duty operations. The continuous stall current of this motor is 2.9 Arms, the maximum current it can supply continuously at stall without going beyond thermal ratings. The electrical design of this motor provides a voltage rating of 240V AC and a 320V DC bus maximum, thus supporting a large variety of industrial power systems.
The voltage constant of this motor is rated at 117 Vrms/kRPM for effective electrical to mechanical energy conversion during operation. The electromagnetic features of this motor consist of a line-to-line inductance of 27.2 mH to provide smooth current regulation and increased control accuracy. This motor’s thermal resistance is 0.78 °C/Watt for effective heat dissipation to support extended operational lifetimes and effective thermal management. The weight of the PMB33C-00201-02 motor without break is 6.3 kg to support effective handling for both vertical and horizontal mounting in compact industrial assemblies.
