PURPOSE: A motor drive control apparatus and air conditioning equipment are provided to reduce current distortion by detecting the position of a rotor in a high and a low speed operation. CONSTITUTION: An inverter(3) changes DC power to AC power. A voltage detection device(5) senses a motor applying voltage. A control device adjusts the inverter with PWM(Pulse Width Modulation). A stop device(7) holds a pulse signal for a stop interval. An adjusting device changes the stop interval. [Reference numerals] (7) Stop device; (8) Adjusting device; |
