	78	+The case of the Lynxmotion PRO Smart Servo is in three parts: the main body, the cap and the mounting plate. Each of these three parts is milled from aluminum and anodized black.
	79	+
	80	+**Main Body**
	81	+
	82	+The main body is in the shape of a compact T, with the stepper motor located in the center.
	83	+
	84	+**Cap**
	85	+
	86	+The cap supports the top and bottom PCB which make up the electronics inside the actuator. The bottom PCB must be located at the rear of the stepper motor in order to make use of the encoder.
	87	+
	88	+**Mounting Plate**
	89	+
	90	+The mounting plate provides a convenient connection point onto which another actuator, clamp or bracket can be connected. As indicated above, it has the mounting pattern for the gearbox output for each of the three servo motors, as well as the clamp.

These motors provide high torque at low speeds, but operate at a set current and therefore do not have a direct way of measuring the torque.
