The air conditioning and refrigeration systems include fans, pumps, and reciprocating, rotary and centrifugal compressors. To effect the transfer or compression of various liquids and gases such as air, water, brine of refrigerants, it is necessary to put this equipment into motion by prime movers, in this instance, electric motors.
Apart from the factors (source of electric energy, speed, power) which are used in the selection of particular motor-starter combinations, a knowledge of the load torque characteristic for a particular driven equipment is the most fundamental requirement.
The operational torque characteristics include those required for starting from rest, acceleration, and for full load running. The starting or locked rotor torque is the initial turning effort for bringing the driven equipment from standstill into motion; the acceleration torque is the developing of this motion into operating speed in as alloted time.
The full load torque is the sustained effort by the motor to maintain the driven equipment in motion under the work load. The driven equipment torque requirements must be matched with a drive complex (motor and its control) of the proper torque and current characteristics.
