Product Description:

Pacific Scientific produces the PMB33F-20114-02 brushless servo motor and it provides dependable performance across various applications. The motor's digital encoder makes it ideal for applications requiring precise accuracy. It is compatible with a wide variety of industrial automation systems due to its NEMA Size 34 frame.

The encoder offers feedback for accurate position control and commutation. For the purpose of ensuring that the motor stays within the parameters that were designed for it when it is at rest, a continuous stall current of 9 A RMS is supplied to the motor all the time. The motor's maximum stall torque is 12.5 Nm, and the winding requires 11.0 A of current. A secure fastening is provided by the square key shafts that come in two and three sizes. When the torque is at its maximum, the servo motor requires a current of 21.2 A RMS. Installation is made easier by the amp connectors and floating leads that it possesses. The PMB33F-20114-02 brushless servo motor is versatile in terms of control and performance, making it useful for a variety of applications. It is possible for this motor to offer reliable feedback even while it is operating at 5,700 revolutions per minute (rpm) without any load because it is equipped with a 2048 ppr sensor.

Furthermore, a digital encoder with commutation is included with the motor. The motor can reach 4,500 rpm, and with its dependable torque characteristics at different speeds, the PMB33F-20114-02 brushless servo motor is designed to operate for a long time in demanding applications. It is perfect for systems that need reliable and accurate performance due to its efficient design and precise control system.
