摘要： A hybrid turbine classifier for a coal pulverizer includes a cone disposed within the separator body of the pulverizer. The cone extends downwardly from a base to a frustum which forms an opening for depositing coal particles on the grinding table of the pulverizer. The outer surface of the cone and the separator body define an outer passage for coal/air flow, containing a mixture of smaller and larger coal particles, from the grinding table. A circular, first classifier cage disposed proximate to the base of the cone defines a circumferential passage between the outer passage and the cavity of the cone. The first classifier cage includes static, circumferentially-spaced vanes which direct the coal/air flow in a spiraling, circular flow path within the cavity. The flow path defines a first flow direction. A circular, second classifier cage is coaxially disposed within the first classifier cage. The second classifier cage includes a rotor which is rotatable around the axis and which defines a circumferential outlet from the cavity. The rotor has circumferentially-spaced blades directing the coal/air flow in a second flow direction opposite to the first flow direction. The vanes of the first classifier cage define a static vane angle selected to direct the coal/air flow tangentially to the blades of the second classifier cage.

摘要： A method of controlling a motor to cause it to execute a move toward a target position including calculating a deceleration position, wherein when the deceleration position is reached, the motor will be caused to execute a deceleration in a manner that will result in the motor stopping short of the target position, and determining whether the requested move is a first move type after the motor has reached the deceleration position and the deceleration is complete. If the requested move is a first move type, the method includes causing the motor to move toward the target position at a first velocity, and if the requested move is a second move type, the method includes causing the DC motor to move toward the requested target position at a second velocity, wherein the second velocity is greater than the first velocity. Settling time is also varied depending on move type.
