[0053] This embodiment provides a motor testing system, such as Figure 1 As shown, the motor test system includes a driver chip 10 and a controller 20; wherein,
[0054] The driving chip 10 is used to generate a driving signal; drive the motor to vibrate through the driving signal, and collect data of the motor during the vibration process;
[0055] The controller 20 is used to analyze the vibration state of the motor according to the data to obtain a vibration state analysis result; and adjust the driving signal according to the vibration state analysis result.
[0056] In this embodiment, the driving signal is an electrical signal. For example, the driving signal may be a voltage signal or a current signal.
[0057] In this embodiment, the data of the motor during the vibration process includes but is not limited to the current value I of the drive signal and the voltage value V of the motor input terminal.
[0058] In this embodiment, the controller 20 may be a microcontroller (MCU), a single-chip microcomputer or a control circuit, or an application processor (AP), a central processing unit (CPU), a graphics processing unit (GPU), etc. The controller 20 is electrically connected to the driver chip 10.

[0059] The motor testing system described in this embodiment can achieve control over motor vibration. Since the driving signal input to the motor can be adjusted according to the collected data, it helps to enhance or optimize the vibration tactile experience.
[0060] based on Figure 1 The motor test system shown, in some embodiments, Figure 2 As shown, the motor testing system also includes:
[0061] A first sensor 30, used to detect first acceleration data of the motor during vibration;
[0062] The controller 20 is further configured to control the vibration of the motor according to the first acceleration data.
[0063] Wherein, controlling the vibration of the motor includes: adjusting the frequency and / or amplitude of the driving signal.
[0064] The first sensor 30 is a sensor capable of detecting acceleration data, for example, the first sensor is an acceleration sensor.
[0065] The first acceleration data includes acceleration data on at least one of the X-axis, the Y-axis and the Z-axis.
[0066] In some embodiments, the controller 20 is further configured to:
[0067] The vibration mode of the motor is determined according to the first acceleration data, and when the vibration mode is not within a preset vibration mode range, the amplitude of the driving signal is adjusted.
[0068] Wherein, the preset vibration mode range includes: there is no acceleration signal in the X-axis and Y-axis directions.
[0069] Exemplarily, when there is an acceleration signal in the Z-axis direction but no acceleration signal in the X-axis and Y-axis directions, it is determined that the vibration mode of the motor is within the preset vibration mode range; when there is an acceleration signal in the X-axis or Y-axis direction, it is determined that the vibration mode of the motor is not within the preset vibration mode range, and adjustments are made, such as reducing the amplitude of the drive signal.
[0070] In some embodiments, the first sensor 30 is further used to detect amplitude data of the motor during vibration; the controller 20 is further used to track or calibrate the resonance state of the motor according to the amplitude data.
[0071] Among them, the controller 20 controls the driving chip 10 to output driving signals of different frequencies and amplitudes to the motor, and collects amplitude data at the same time. When the amplitude value in a certain vibration direction reaches the maximum point, the corresponding driving signal at this time is the resonant driving signal, and the corresponding frequency at this time is the resonant frequency f0.
[0072] In this way, the motor detection system can be used to track or calibrate the resonance state. The motor test system can be used to calibrate the resonance frequency f0 in the resonance state. For example, the motor test system can be used to calibrate f0 in real time at any time, such as when a temperature change is detected.

[0074] Wherein, controlling the vibration of the motor includes: adjusting the frequency and / or amplitude of the driving signal.
[0075] The second sensor 50 is a sensor capable of detecting acceleration data, for example, the second sensor is a pressure sensor.
[0076] Wherein, the second acceleration data includes: acceleration data on the Z axis.
[0077] based on Figure 1 In the motor testing system shown, in some embodiments, the data of the motor during the vibration process includes voltage value and / or current value; the controller 20 is also used to monitor and detect the vibration state of the motor according to the voltage value and / or the current value; and determine the vibration model according to the monitoring and detection results.

[0079] In this way, the motor testing system can model the motor and solidify the vibration model of the motor under certain voltage and frequency conditions. When different vibration effects are required, any vibration effect can be achieved by splicing the corresponding vibration models.
[0080] In some embodiments, the motor testing system can control the driving chip 10 under the same driving waveform by the controller 20 to collect the motor vibration signal, voltage V and current I, and achieve the consistency of motor vibration by compensating the driving signal. If the resistance is consistent and the driving signal given by the signal link is consistent, the consistency detection of the vibration effect of the motor can be achieved by compensating the driving signal.
[0081] based on Figure 1In the motor testing system shown, in some embodiments, the driver chip 10 is also used to detect the size of the sound generated by the vibration of the motor; the controller 20 is also used to obtain the size of the sound generated by the vibration of the motor; and whether the motor is damaged is determined based on the size of the sound.
[0082] In some embodiments, the controller 20 determines whether the sound generated by the motor vibration exceeds a preset sound level; when the sound level exceeds the preset sound level, it is determined that the motor is damaged or there is a risk of damage to the motor.
[0083] In this way, the motor testing system can detect whether the motor is damaged, thereby helping to indicate whether the motor needs to be replaced.

The motor testing system generates a driving signal through a driving chip, and amplifies the driving signal to drive the motor to vibrate. When the motor vibrates, the internal magnetic field changes. The controller analyzes the vibration state of the motor through the data of the motor vibration sensed by the first sensor or the second sensor; or analyzes the vibration state through the voltage and current detected when the motor vibrates. The controller adjusts the driving signal output by the driving chip according to the motor vibration state, thereby realizing vibration control, modulation, optimization, problem analysis, etc. of the motor.
