... To accommodate various motor applications, the MTD6505 provides options to facilitate diverse BEMF coefficients. The MTD6505 defines BEMF coefficient (Km) as the peak value of the phase-to-phase BEMF voltage, normalized to the electrical speed of the motor. The following table offers methods to set the Km value for the MTD6505 device ...
