摘要： Abstract A control system for an electric pump, the control system comprising an input and an output electrically connectable to, respectively, a power source and the electric pump. The control system also comprises a controller configured to cause variable electrical power to be supplied to an AC motor of the electric pump via the output and thereby control a rotational speed of the AC motor. The controller is connectable to a user control device and is selectively switchable between first and second motor operating modes using the user control device, wherein for the first of the motor operating modes the AC motor is a synchronous AC motor and for the second of the motor operating modes the AC motor is an asynchronous AC motor. The control system also comprises a storage device coupled to the controller that stores at least one set point relating to an operating environment of the electric pump. The controller is further configured such that in response to receiving signals from one or more pump operating sensors, the controller automatically varies the rotational speed of the AC motor to thereby maintain the set point. The set point is either (a) a constant fluid flow rate and the controller increases or decreases the rotational speed of the AC motor when the signals indicate that a fluid flow rate in the operating environment is, respectively, less than or more than the constant fluid flow rate, (b) a constant fluid pressure and the controller increases or decreases the rotational speed of the AC motor when the signals indicate that a fluid pressure in the operating environment is, respectively, less than or more than the constant fluid pressure or (c) a constant fluid level and the controller increases or decreases the rotational speed of the AC motor when the signals indicate that a fluid level in the operating environment is, respectively, more than or less than the constant fluid level. In the first of the motor operating modes, the synchronous AC motor is a brushless permanent magnet AC motor. a) 0. I:i c) J CD U-U ,It * F 0 * ~c) -__ - . . - . - . .
