Brand: A-B
Model: MPL-B430P-MK74AA
The MPL-B430P-MK74AA is part of Kinetix MPL’s low inertia servo motor. This servo motor is 400v class, brushless AC synchronous servo motor. It has a frame size of 115 mm, a magnet stack length of 76.2 mm (3.0 in), and a rated speed of 5000 rpm. The servo motor has built-in multi-turns, 1024 sin/cos, absolute encoder (Hiperface protocol), as a feedback device. The MPL-B430P-MK74AA servo motor is equipped with an integrated 24-volt DC braking unit. It has no shaft key and no pre-applied shaft seal.
MPL-B430P-MK74AA servo motor refers to the engine that controls the operation of mechanical components in the servo system, which is a supplementary motor indirect transmission device. The servo motor can control the speed, the position accuracy is very accurate, and the voltage signal can be converted into torque and speed to drive the control object. Servo motor rotor speed is controlled by the input signal, and can react quickly, in the automatic control system, used as an executive component, and has a small electromechanical time constant, high linearity characteristics, the received electrical signal can be converted into the angular displacement or angular speed output on the motor shaft.
MPL-B430P-MK74AA servo motor is divided into DC and AC servo motor two categories. Its main feature is that when the signal voltage is zero, there is no rotation phenomenon, and the speed decreases uniformly with the increase of the torque.
The MPL-B430P-MK74AA 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.
