This disclosure relates to an electromagnetic brake (22) configured to slow a deceleration rate of a passenger conveyer, such as an elevator car, during braking. In particular, this disclosure relates to a passenger conveyer system including the electromagnetic brake (22) and a corresponding method. An example system includes a controller (28) and an electromagnetic brake (22). The electromagnetic brake (22) includes a disc (32) configured to interface with a drive shaft, a spring (38), and a plate (36) biased in a first direction (Di) into engagement with the disc (32) by a bias force of the spring (38). The electromagnetic brake (22) further includes an electromagnet (42) selectively activated in response to a command from the controller (28) to produce a magnetic field attracting the plate (36) in a second direction (D2) opposite the first direction (Di) to partially offset the bias force of the spring (38). Further, when the electromagnet (42) is activated, the plate (36) engages the disc (32).
