How do you think a motor is an ordinary motor or a servo
The servo motor must have encoder, this is the most obvious characteristic, besides, the servo motor is generally square.
Different methods: Common motor is a radiator in the rear, general motors are cast iron case The servo motor is a coder with no cooling fan, usually aluminum Servo motor Open classification: machine, motor Noil definition: the engine that controls the operation of the mechanical component in the servo system. Noil effect: servo motor, can make control speed, position precision is very accurate. The voltage signal is converted into torque and rotational speed to drive the control object Noil classification: dc servo motor and ac servo motor.
There is another communication cable interface. General servo motor will be in the position sensor, such as possibly braking device, the device control and information feedback is generally via a special communication cable. But not get communication cable is servo motor, some contain many large motor temperature sensor (bearing, winding), such as also need special communication cable, but it is not servo motor. In addition, many servo motor enclosures are square, and ordinary motors are round.
The step motor is an ordinary open-loop motor, the back end of the servo motor is an encoder device, the motor with the coder feedback. Ordinary stepper motor speed is generally around 300-600, the speed of the servo motor, generally can reach 3000 turn above, higher precision, but the cost is much higher than ordinary servo stepper motor. Now our company has developed a new step servo motor based on the basic step motor and servo motor. The cost is low, the price ratio is high, the coder feedback is accurate, listen to the friend to say to use very good!
