(1) Obtain the value of PH that corresponds to the motor coil current IO from Fig. 6 "Heat dissipation per phase PH vs. Out- put current IO." (2) The power dissipation Pdiss is obtained using the following formula. 2-phase excitation: Pdiss ≅ 2PH+0.015×VS (W) 1-2 phase excitation: Pdiss ≅ PH+0.015 ×VS (W) (3) Obtain the temperature rise that corresponds to the calcu- lated value of Pdiss from Fig. 7 "Temperature rise." 3 2 |
