PURPOSE:To control the drive of a DC motor always with constant torque irrespective of the variation in the temperature of the motor by compensating the current corresponding to a torque command on the basis of the temperature of a field magnet. CONSTITUTION:A temperature detector 12 is composed...
The expression in the equation (2) is known as the armature torque of DC motor. For a given DC motor, the (PZ/2πA) is a constant. Hence,τa∝φIa…(3)τ𝑎∝φ𝐼𝑎…(3)Therefore, the armature torque developed in a DC motor is directly proportional to the flux per pole ...
PURPOSE:To control a torque at constant of the motor, by such means that a required current set value be divided to be processed operation by a value corresponding to a field quantity of the DC machine to be controlled, with this arithmetic value inputted as a set signal to a current cont...
Is the torque constant of a DC motor the same regardless of voltage? Hi, we know that the speed varies inversely with the torque. The more the torque, the lower the speed. From torque-speed curve, we can calculate the slope. When the applied voltage increases, the straight line shifts ...
A new sensorless control algorithm for brushless dc motors (BLDCMs) is proposed in this paper. The torque constant of a BLDCM is used as a reference signal for position detection because it is constant during the entire speed range and can be estimated by calculating the ratio of the back ...
