This is because the torque developed by a synchronous motor is proportional to the sine of the load angle. When the load angle is 45\u00c2\u00b0, the sine of the load angle is 0.707, which is the maximum value of the sine function. Therefore, the synchronous motor develops maximum power when the load angle is 45\u00c2\u00b0.<\/p>\n<p>The other options are incorrect because they do not correspond to the maximum power point of a synchronous motor. When the load angle is 0\u00c2\u00b0, the torque developed by the motor is zero. When the load angle is 90\u00c2\u00b0, the torque developed by the motor is also zero. When the load angle is 120\u00c2\u00b0, the torque developed by the motor is negative. Therefore, the synchronous motor does not develop maximum power when the load angle is 0\u00c2\u00b0, 90\u00c2\u00b0, or 120\u00c2\u00b0.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;45\u00c2\u00b0&#8221;
