The brushes can be moved to align the rotor windings with the stator field in different ways. When the brushes are aligned with the stator field, there is no torque produced and the motor stops. When the brushes are at 90\u00c2\u00b0 electrical to the stator field, the maximum torque is produced.<\/p>\n<p>Option A is incorrect because when the brush axis is 45\u00c2\u00b0 electrical to the field axis, there is a small amount of torque produced.<\/p>\n<p>Option B is incorrect because when the brush axis coincides with the field axis, there is no torque produced.<\/p>\n<p>Option D is
