Hi, what are you looking for?

There are many types of motors available on the market, such as ordinary motor, DC motor, AC motor, synchronous motor, asynchronous motor, geared motor, stepper motor, and servo motor, etc. Are you confused by these different motor names? Jiangyin Gator Precision Mold Co., Ltd., a comprehensive enterprise integrating mold manufacturing, silicon steel sheet stamping, motor assembly, production and sales, introduces the differences between stepper motor and servo motor. Stepper motors and servo motors are almost same usage for positioning but are entirely different systems, each with its pros and cons.

Stepper motor is an open-loop control element stepper motor device that converts electrical pulse signals into angular or linear displacements. In the case of non-overload, the motor speed and stop position only depend on the frequency of pulse signal and the number of pulses, and are not affected by load changes. When the stepper driver receives a pulse signal, it drives the stepper motor to turn a fixed angle in the set direction (such angle is called “step angle”), according to China stepper motor factories. The amount of angular displacements can be controlled through controlling the number of pulses, so as to achieve the purpose of accurate positioning; the speed and acceleration of motor rotation can be controlled through controlling the pulse frequency.Features: High torque in low speed; faster positioning time during short strokes; no hunting during stop position; high tolerance movement of inertia; suitable for low-rigidity mechanism; high responsiveness; suitable for fluctuating loads.

Servo motor, also known as actuator motor, is used as an actuating element in automatic control systems to convert the received electrical signal into an angular displacement or angular velocity output on the motor shaft. The servo motor rotor is a permanent magnet and rotates under the action of the magnetic field, while an encoder coming with the motor feeds back signal to the driver. By comparing the feedback value with the target value, the driver adjusts the angle of rotor rotation.Servo motor is positioned mainly relying on pulses, which means that the angle of one pulse will be rotated to achieve displacement when the servo motor receives one pulse, because the servo motor itself has the function of sending out pulses. By doing so, the rotation of motor can be controlled very precisely, thus achieving accurate positioning. Features: High torque in high speed; faster positioning during long strokes; hunting during stop position; low tolerance movement of inertia; not suitable for low-rigidity mechanism; low responsiveness; not suitable for fluctuating loads.
