1. A compactor comprising:
a plate;
an electric motor coupled to the plate and including a motor shaft configured to rotate about a rotational axis;
an exciter coupled to the plate and configured to vibrate the plate in response to receiving torque from the electric motor, wherein the exciter includes an exciter shaft and an eccentric mass attached thereto, wherein the exciter shaft is configured to receive torque from the motor shaft to rotate the eccentric mass to impart vibration to the plate, and wherein the exciter shaft is parallel with the rotational axis;
a battery configured to provide power to the electric motor; and
a gear train to transfer torque from the motor shaft to the exciter shaft, wherein the gear train permits the exciter to be driven at a rotational speed that is faster than, slower than, or a same speed as a rotational speed of the electric motor.
