1. An icemaker comprising: a casing defining an interior volume; a water supply for selectively providing water into the interior volume; a sealed system comprising an evaporator in thermal communication with the casing for selectively freezing the water; an auger mounted within the interior volume, the auger being rotatable to scrape the ice from the casing; a brushless direct current (BLDC) motor mechanically coupled to the auger to selectively rotate the auger; and a controller in operative communication with the BLDC motor, the controller being configured to: obtain an ice production parameter from a user of the icemaker; determine a target speed of the auger based at least in part on the ice production parameter; and operate the BLDC motor to rotate the auger at the target speed and generate ice in accordance with the ice production parameter.
