Are DC motors reversible?

Simply put, DC motors can turn in either direction (clockwise or counter-clockwise) and can be easily controlled by inverting the polarity of the applied voltage. Strictly speaking, the motors can actually create a force in either direction. We make this important distinction because some applications, such as Continue reading

Visualising Voltage, Amplitude, and Frequency Relationships in 3D

We’re often stressing how a vibration motor’s voltage, vibration amplitude, and vibration frequency are interrelated – essentially the voltage controls the motor speed which in turn directly affects the frequency and amplitude. Application Bulletin 029 covers this in full. Other factors obviously help determine the profile Continue reading

VAB-02 Released : How Do Vibration Motors Work?

Our latest Video Application Bulletin looks at how eccentric rotating mass vibration motors work. It’s the type of application that really lends itself to animation, where we’re able to show you exactly how the motor’s movement creates a displacement. We also discuss what aspects of the ERM affect the Continue reading
