Product Description:
The PMB33E-00101-02 Brushless Servo Motor features a NEMA 34 frame. It delivers reliable power and control in a compact and robust form factor. Its flat shaft design and low inertia rotor construction make it suitable for responsive and precise movement.
This PMB33E-00101-02 servo motor from Pacific Scientific ensures stable torque delivery under consistent load conditions with a continuous stall torque rating of 5.42 Nm. This motor incorporates an 8 pole synchronous construction that optimizes performance for closed loop motion systems. The rotor of this motor is embedded with neodymium iron boron magnets which provide strong magnetic fields for maximum torque efficiency. The voltage constant (line to neutral) is rated at 0.56 V_RMS/rad/sec that supports accurate velocity control. It operates at a maximum of 240 V AC or 320 V DC on the bus. This provides flexible integration with various servo drive systems. The motor’s peak torque capability draws 17.5 A_RMS that allows short term overload without compromising system safety. Its resistance between lines is 2.2 Ohms and the thermal resistance is 0.78 °C/W. This allows for efficient heat dissipation during prolonged operation. The motor employs flying leads terminated with AMP connectors that simplifies installation and maintenance procedures. It is constructed to IP40 standards that provides protection against solid objects greater than 1mm in size.
A PTC thermistor is embedded in this PMB33E-00101-02 servo motor for overheating protection. The shaft of the motor features a flat design to enhance coupling security in mechanical assemblies. The motor’s rotor inertia is rated at 0.404 ×10⁻³ kg·m². The motor is designed for durability and electrical reliability. The static friction is capped at 0.169 Nm that enables smooth start up and reducing mechanical wear.
