We are professionally engaged as manufacturer, supplier and exporter of AC Servo Motor Study in Roorkee, Uttarakhand, India.
* Torque computation through electrical loading
* Determination of motor parameters - inertia and friction
* Digital display of time constant
* Transfer function evaluation
Two phase a.c. servomotor is one of the very important electromechanical actuators having applications in the area of control systems. The study of its operating principle and features form a part of the first course on automatic control systems in electrical engineering curriculum. It's small size, low inertia and almost noise and frictionless operation makes the a.c. servomotor particularly attractive in aircraft and spacecraft applications.
The characteristics of an a.c. motor is usually non-linear. To simplify the analysis a linearized model is developed. The experimental work rev-olves around determination of the parameters of the motor and thus its transfer function.
Important subsystems of the unit includes,
(a) an integrated speed sensor with 4-digit display in r.p.m.
(b) an electrical loading system to compute torque
(c) a time-constant measurement circuit with 3-digit display in milli seconds
(d) a three step a.c. source with built-in r.m.s. voltmeter, and
(e) a digital voltmeter on the panel for load measurement
