Brand: A-B
Model: MPL-B430P-SJ24AA
Description: This Allen Bradley (AB) MPL series servo motor is rated for 5000 rpm AC servo. In addition, this smart servo has a shaft key installed in the servo to allow connection to this motor. In addition, it features single-turn feedback and has a circular bayonet (facing shaft) cable connection to come on top of this motor. This MPL series premium servo is equipped with a built-in braking function in case braking is required. This MPL series AC servo operates at 400 volts.
The MPL-B430P-SJ24AA servo motor is a motor used to control mechanical equipment, which can convert the input electrical signal into the angular speed or linear speed output of the motor shaft to achieve accurate position control, speed control and torque control. Servo motor has the advantages of high precision, high efficiency, fast response and good stability, and is widely used in robot, CNC machine tool, automatic production line and other fields.
The MPL-B430P-SJ24AA servo motor and stepper motor are significantly different in several aspects:
Control mode: The stepper motor controls the rotation Angle by controlling the number of pulses, and one pulse corresponds to one step Angle. The servo motor controls the rotation Angle by controlling the length of the pulse time.
Workflow: Stepper motor work generally requires two pulses: signal pulse and direction pulse. The work flow of the servo motor is relatively simple, the power is connected to the switch, and then the servo motor can be connected.
Low frequency characteristics: The stepper motor is prone to low frequency vibration at low speed. In contrast, the servo motor runs very smoothly and does not vibrate even at low speeds.
Torque frequency characteristics: the output torque of the stepper motor decreases with the increase of speed, and it will drop sharply at higher speed, so its maximum working speed is generally 300 ~ 600r/min. The servo motor is a constant torque output, that is, within its rated speed (generally 2000 or 3000 r/min), the output rated torque, above the rated speed is a constant power output.
Overload capacity: Stepper motors generally do not have overload capacity. The servo motor has a strong overload capacity.
In summary, there are significant differences between servo motors and stepper motors in terms of control mode, workflow, low frequency characteristics, moment frequency characteristics and overload capacity. In practical applications, the appropriate motor type should be selected according to the specific needs.
