摘要

A method for starting and operating a shape memory alloy - (sma -), the thermal power machine (14; 54) with a first rotatable belt pulley (38; 78), a second rotatable belt pulley (40; 80) and an sma - material (22), which surrounds the first and second rotatable belt pulley (38; 78; 40; 80) and between a hot area (18; 68) and a cold region (20; 70) is arranged, wherein the method comprises:Detecting a thermal energy gradient between the hot area (18; 68) and the cold area (20; 70) with the use of a controller (32);Decoupling of an electrical generator of one of the first and second rotatable belt pulley (38; 78; 40; 80);Monitoring a rotational speed of the sma - material (22) about the first and second rotatable belt pulley (38; 78; 40; 80);Re-engagement of the electrical generator, when the monitored speed of rotation of the sma - material (22) exceeds a threshold;Monitoring a temperature of the sma - material (22);Modifying a transmission ratio of an adaptive torque adjusting device, which between the electrical generator, and of the rotatable belt pulley (38; 78; 40; 80) is arranged, in order to provide a ..
