2012-2-24 Separately Excited DC Servo Motor DC Servo Motor Theory. The motors which are utilized as DC servo motors, generally have separate DC source for field winding and armature winding. The control can be archived either by controlling the field current or armature current. Field control has some specific advantages over armature control and on the other hand armature control has also some specific advantages over field control.

2017-1-6 A DC servo motor is used as an actuator to drive a load. It is usually a DC motor of low power rating. DC servo motors have a high ratio of starting torque to inertia and therefore they have a faster dynamic response. DC motors are constructed using rare earth permanent magnets which have high residual flux density and high coercively.

2 天前 The DC servo motor is more common in small robotic joints, camera auto focusers, antenna positioning systems, RC vehicles, etc., and often uses brushed DC motors with a gear set to increase torque. Servo motors are a highly precise alternative to DC motors and they are quickly becoming the preferred choice if cost is not of primary concern.

2018-12-5 We can talk about servo motors as an assembly of four things: a DC motor, a gearing set, a control circuit and a position-sensor (usually a potentiometer). In industry servo motors are known as motors that can be controlled most precisely. Comparing servo with standard DC motors, servos usually have three wires (power, ground and control).

Speed Torque Characteristic of DC Servo Motors. One of the important properties of DC motor is its speed torque characteristic. Ideally when the voltage is connected to the motor, it must provide a constant torque to accelerate the rotor and when the required speed is reached the torque must become zero. This is shown in Fig. 4.5.

This is typical of a DC motor where the mechanical dynamics are much slower than the electrical dynamics, and hence dominate the response. (3) In addition to the fact that our model is reduced-order, the model is a further approximation of the real world in that it neglects nonlinear aspects of the true physical motor. Based on our linear model ...
