2000 series two-speed motors
Danfoss 2000 series motors are available with an integral two-speed feature that changes the displacement in a ratio of one to two and shifts the motor from a low-speed, high-torque (LSHT) mode to a high-speed, low-torque (HSLT) mode. The open-center selector valve shifts the speed mode from low to high when a pilot pressure of at least 6.9 dbar [100 dpsi] over case pressure is applied to the pilot port. In the high-speed mode, torque values are approximately one-half those of the conventional 2000 series single-speed motors, and speeds are approximately double.
