A linear actuator or motor for oscillating a blade is provided. The linear actuator replaces an eccentric drive and yoke, resulting in a linear powered drive to oscillate the blade linearly. This operation facilitates the formation of a smaller and/or lighter hair clipper. The linear actuator uses alternating current to oscillate a permanent against a biasing force produced by a set of springs. The permanent magnet is located opposite a stator with an electromagnetic coil that generates an electromagnetic force to oscillate the permanent magnet.
