Chopper Drive as you refer to it is a method of current limiting. This is necessary when a power supply voltage higher than the rating of the motor is used. Current limiting resistors can also be used inplace of a chopper. Current limiting resistors will disipate heat and be large in wattage value if the power supply is significanly higher that the motor rating.
