The invention discloses a speed giving driver controller of an
electric locomotive. The speed giving driver controller comprises a non-
contact angle sensor, a logic operation
control unit, a speed control remover, a digital display tube and a
buzzer, wherein the logic operation
control unit is connected with the non-
contact angle sensor, the speed control remover, the digital display tube and the
buzzer respectively; and the logic operation
control unit is further provided with an actual locomotive speed
signal connector, a limited speed
signal connector, an instruction
signal output connector, and I-grade, II-grade and III-grade
magnetic field weakening signal output connectors. The speed giving driver controller of the
electric locomotive has the beneficial effects that the non-
contact angle sensor is adopted and an instruction signal is stable; a fault caused by abrasion is avoided and maintenance-free operation can be realized; locomotive constant-speed giving is automatically controlled and the speed giving driver controller effectively guarantees that the locomotive can operate safely at the highest speed; magnetic weakening is automatically controlled; and after a speed
control function is removed, all functions of a common driver controller can also be finished.
