WebPumping applications can be categorized as constant torque (CT) or variable torque (VT). This refers to the relationship of the torque required by the pump to a reduction in speed. Positive displacement pumps can be slowed to decrease the flow rate but the pressure may be constant. For example, if a gear pump is used to pump hydraulic oil to … Web14 de dez. de 2024 · The performance analysis of two current control techniques for the control of permanent magnet synchronous motor (PMSM) drive is investigated in this paper. Constant torque angle control strategy is employed for the outer speed control loop to obtain maximum torque per unit current. In enhancing the drive system dynamics, the …
WebDrive Application Notes Constant Torque Applications For constant torque loads, the load torque remains constant throughout the speed range, as shown in Figure 1. The horsepower changes linearly with speed for these loads. Machines that are high impact loads or duty cycle loads typically fall into the constant torque classification. WebThe term torque (from Latin torquēre "to twist") is said to have been suggested by James Thomson and appeared in print in April, 1884. Usage is attested the same year by Silvanus P. Thompson in the first edition of Dynamo-Electric Machinery. Thompson motivates the term as follows: Just as the Newtonian definition of force is that which produces or tends …
