'Delta' textile motors are suitable for use in Silk, Cotton and Synthetic Fiber textile mills and power looms. It has got smooth acceleration, high torque, noiseless performance. They are either supplied in TESC or TEFC design. For highspeed looms these motors can be supplied with 24 Volts D.C. disc brake. The brake is mounted on non-driving end and it works as under.
(1)	Operation :-
	Under no power conditions to the motor the brake armature coil mounted on non-driving and endshield get energized with sperate 24 Volts D.C. Supply, supplied through NO/NC contact of a contractor, hence the armature attracts the disc allowing the rotor to rotate freely. When breakage of thread takes place during weaving, in a high speed loom, the supply to the motor is immediately disconnected. As soon as the power to the motor is disconnected the armature coil get energized which instantly attracts armature disc overcoming the spring force resulting almost instantenous stopping of rotor thus fail safe condition is ensured.
