Latest Patents

One of Pratt's notable patents is a method for increasing the speed of an alternating current motor. This motor control method involves connecting a drive motor to an adjustable frequency power supply, allowing for selective variation of the frequency supplied to the motor. While the motor operates at a constant speed, the current supplied is monitored, and a comparison is made with a reference current signal. If the actual current is within limits, the frequency can be increased, thereby enhancing the motor's speed. Another significant patent is a method and apparatus for detecting mechanical overload of a hoist. This system compares the current supplied to the motor with a reference level indicative of a mechanical overload condition. If the actual current meets or exceeds this reference, an overload signal is generated, ensuring safety during operation.
