1326AB-B740E-M2L servo motor to achieve accurate control of the motor running state

The 1326AB-B740E-M2L servo motor is the Allen-Bradley/ Rockwell Automation announcement 1326 Torque Plus series of servo motors. It can operate at a maximum speed of 3,400 RPM, with a maximum output power of 12.7 kW, and rated motor torque of 50 N-m or 450 pounds per inch at a rated motor voltage of 460 volts AC. The 1326AB-B740E-M2L servo motor also supports continuous stall ratings of 32 amps and peak stall ratings of 33.2 amps or 50 amps. The peak stall current rating depends on the type of Allen-Bradley Bulletin 1394 shaft module used by the motor. The 1326AB-B740E-M2L servo motor uses a 4-inch ferrite magnet stack to reduce friction.

The process by which the 1326AB-B740E-M2L servo motor converts voltage signals into torque and speed involves multiple factors and complex physical principles. Here’s a simplified explanation:

Voltage signal: The voltage signal received by the 1326AB-B740E-M2L servo motor is actually an instruction to control its operation. This signal indicates the desired speed or torque.

Internal circuit: There is a complex circuit system inside the servo motor, including power supply, control circuit, power drive circuit, etc. This circuit system is responsible for converting the input voltage signal into the actual operation instructions of the motor.

 

Magnetic field and current: The working principle of 1326AB-B740E-M2L servo motor is based on the interaction of magnetic field and current. When an electric current passes through the coils of a motor, it creates a magnetic field. This magnetic field interacts with the permanent magnetic field inside the motor to produce torque.

Torque and speed: Torque is the torque of the motor rotation, and speed is the speed of the motor rotation. The torque and speed of the servo motor can be controlled by adjusting the input voltage signal. The amplitude and frequency of the voltage signal affect the torque and speed of the motor. In general, higher voltages produce greater torque, and higher frequencies lead to faster rotational speeds.

Feedback system: The 1326AB-B740E-M2L servo motor usually contains a feedback system inside, which feedbacks the actual operating state of the motor (such as torque and speed) to the controller. The controller uses the feedback information to adjust the input voltage signal, so as to achieve accurate control of the motor running state.

The above process is a simplified explanation, the actual servo motor control system is much more complex, and involves many other factors and principles, such as thermal effects, mechanical loads, control algorithms, etc. If you have more in-depth questions about this topic, it is recommended that you consult a professional mechanical engineering expert or consult the relevant professional literature.
