An essential tool for determining the motor's speed and angular displacement is the servomotor encoder. However, frequent use or other factors could cause the encoder to malfunction. This post will discuss a few typical servo motor encoder problems and offer helpful maintenance advice. 1. Encoder signal loss: This can be brought on by a malfunctioning encoder, a damaged cable, or a bad cable connection. Replacing damaged cables, inspecting and re-connecting cables, and changing the encoder are some solutions. 2. Inaccurate encoder readings: This could be brought on by a dirty, damaged, or improperly calibrated encoder. Replacing the malfunctioning encoder, performing error calibration, and inspecting and cleaning the encoder are some solutions. 3. Vibration or noise from the encoder: This could be the result of a loose, unsteady, or broken encoder. Reinstalling the encoder, tightening it up, or changing the damaged encoder are some solutions. 4. Encoder ... Continue reading →

Stepper drivers are very important for the normal operation of stepper motors and brushless DC motors, so in order to make the motor work better, we need to understand the stepper driver. Today, let us first take a look at the signal output ports ALM and BRK of the driver. Please note that if you only control stepper motor operation, then you do not need to connect ALM and BRK. Because they are only used to output signals and are not used to control the motor. Here are some descriptions of these two ports: 1.ALM ALM is the alarm signal output port. When using it, it needs to be connected to the signal receiving end of the driver. There are two wiring methods for the ALM port, as shown below: When the driver sends an alarm, the internal switch between ALM+ and ALM- is closed and an alarm signal is output to the controller. 2.BRK BRK is the brake signal output port. When using it, you need to connect the relay and the brake of the motor. The wiring method is as follows: When the driver ... Continue reading →

Cause of motor heating For any motor icluding sevomotor spindle motor, brushless dc motor,etc,It is normal to heat up during operation, and the same is true for stepper motors. The interior of the stepper motor is composed of an iron core and a winding coil. The resistance of the operation and maintenance winding exists, and the current flowing through the motor will cause loss. The loss is proportional to the square of the resistance and the current, which is called "copper loss". In addition, there is a hysteresis eddy current effect in the iron core, and losses will also occur in the alternating magnetic field. Its size is related to material, current, frequency and voltage, which is called "iron loss". Both copper loss and iron loss will be expressed in the form of heat, affecting the efficiency of the motor. Because stepping motors generally pursue positioning accuracy and torque output, they have low efficiency and large current. The harmonic component is ... Continue reading →

When using T6 servo motor, if jitter occurs, you can eliminate it through the following methods. When the brake is open, the mechanical installation is balanced, the coupling does not shift, the gear meshes well, the encoder wiring is correct, and there is no interference, adjust the inertia, rigidity and other parameters of T6. 1. The wiring is correct (the motor will be automatically recognized by the driver). 2. Use the “operation test” to test whether the motor is running normally. 3. Set the Pr400 value (external servo on signal Pr400=83; internal signal Pr400=3). 4. Select the control mode Pr0.01. (0: Position mode, 1: Speed mode, 2: Torque mode). 5. Connect the motor to the load and adjust the inertia ratio (Pr0.04). Before setting other parameters (such as PID settings for position loop or speed loop), it is very important to find out the inertia ratio of each axis so as to obtain the best performance. If an axis needs to be tested, connect the motor to ... Continue reading →

Encoders, reducers, brakes, and other configurations are added to stepper motors to enhance their performance, range of applications, and other aspects of their design. So what exactly is a stepper brake motor? The purpose of the so-called braked stepper motor is to equip the stepper motor's tail with a brake mechanism. The braking device separates from the stepper motor output shaft when the motor is powered on, enabling the motor to function normally. The brake is also powered on when the stepper motor is. The brake releases forcefully to grasp the motor shaft when the power is cut off. Learn why it's important to start and stop a stepper motor frequently to make sure it's locked or powered on when it's not. What are brake stepper motor characteristics? Stepper motors can precisely convert electrical energy into mechanical energy to achieve angular or linear displacement. They are powered by electromagnetic force. It responds rapidly, rotates smoothly, and steps with ... Continue reading →

The structural differences are:   A linear motor, also called a linear motor, is a mechanical device that converts rotational motion into linear motion. From the perspective of motion principles, to convert a stepper motor from rotational motion to linear motion, the simplest design is to integrate the screw nut into the stepper motor, and realize the entire linear transformation inside the motor. This method greatly simplifies the entire structural design, and in many application fields can directly use linear motors for precise linear transmission without installing external mechanical linkage devices. The basic principle is to install a nut in the center of the rotor of the linear motor, and accordingly use a screw rod to mesh with the nut. In order to move the screw rod forward and backward, some method must be used to prevent the screw rod and the rotor assembly from rotating together. Since the rotation of the screw is constrained, the screw achieves linear motion when the ... Continue reading →
