Provided is a broadband and large displacement angular vibrator, comprising an outer housing, a vibration table, a main spindle, a moving coil assembly, a magnetic circuit assembly, a holding brake assembly, a motor and closed loop control assembly thereof, an electric viscoelastic feedback control assembly, an air bearing, and an angular displacement sensor; the moving coil comprises a moving coil substrate and a coil; the moving coil substrate is fixed to the main spindle; the magnetic circuit assembly comprises a magnetic ring, a central magnetic pole, and magnets; the magnetic ring, central magnetic pole, magnets, and air gap form a closed magnetic circuit; the central magnetic pole is located inside the magnetic ring, the magnets are located between the magnetic ring and the central magnetic pole, and the magnets are attached to the central magnetic pole; the outer housing has the holding brake assembly; the holding brake assembly comprises a brake lining, an oil distribution sleeve, and an oil reservoir having a piston; the brake lining and the oil distribution sleeve enclose a hydraulic oil chamber; when the hydraulic oil is pressed into the hydraulic oil chamber from the oil reservoir, the magnetic circuit assembly brakes; when the hydraulic oil flows back to the oil reservoir, the magnetic circuit assembly rotates with the motor rotor. The present angular shaker has the advantage of being able to switch between intermediate-frequency and low-frequency, and has small output waveform distortion.
