Many safety features such as current control and temperature control features. Software with documentation and support. A Hall-effect sensor is a long-lasting solution because there are no mechanical parts to wear down over time. For closed-loop speed control there are two additional requirements, measurement of the motor speed and/or motor current and PWM signal to control the motor speed and power. However, first we need to clarify what we mean by control when discussing motor drives: To control or not to control. *C 4 Note that the pairs of MOSFETs on the same phase (for example, Q1 and Q2) must not be turned ON at the same time - the resultant low resistance causes high currents that can damage the MOSFETs.
