Crosscheck that proper voltage supply is given to the motor
Are lead wires properly and firmly connected?
Is the load too large or mechanical alignment correct?
If lead wires have been extended by using a terminal strip or terminal block,
are the lead wires properly and firmly connected at all points?
Is wiring correct as instructed in the wiring diagram?
Is the capacitor properly connected and is not leaked (for Single Phase Motors).

Did you view the motor from the wrong direction? ( The connecting
diagram is shown assuming that you view the motor from the flange
surface of the motor ). Remember that the direction of rotation of the
output shaft may be reversed due to reduction ratio of the gearhead. .

Is any screw of terminal box or fan cover changed to a longer one?
Is any foreign particle gone inside the motor body?

This is a motor having fail safe (Power off activated) brake. The motor starts rotation only after power supply is connected to brake and the motor.
The motor gives humming sound if shaft / rotor cannot rotate even after the current flows through it.
This indicates that the brake remains applied and does not allow the shaft to rotate.
Just to crosscheck, separate motor from gearbox and check whether the operation of motor is correct. When power supply is given to brake only (No power should be given to motor winding), the shaft of motor can be rotated easily by fingers. When the power supply to brake is disconnected, the shaft cannot be rotated easily.
