	Presently, motors that are installed in electrical drives require adjustment of speed or position or the both values simultaneously. It concerns not only simple drives of open-circuit speed control but also complex elevator drives and servo-drives that find ever-wider application. DC motors that initially dominated in the industry applications presently get replaced by AC motors as due to a huge development in the do-mains of power electronics and microprocessor technology the AC motor control is as simple and inexpen-sive as it is in the case of DC motors. The paper determines necessary conditions for a drive system that concern asynchronous motor control and follow from the need to ensure adequate torque overload capacity and a slip value. The requirements can be realized in drive systems by controlling amplitude and frequency of the feeding voltage. The following mathematical models of an asynchronous machine have been described: phase model, vector model and a model expressed in relative units. The models are considered as an introduction to further con-siderations on the control of asynchronous motors. Significant scalar control techniques for controlling speed and torque in such motors have been presented. A set of methods for the motor flux stabilization as well as a control with the rotor slip stabilization have been discussed.
