Company Confidential Motor Test Data 2/18/03 EXTERNAL CONTROL MODULE DATA SHEET Description: The External Control Module simplifies the connection of an external motor drive to the Dynamo motor by providing the user with a standard set of hall signals, numerous encoder options, and a high current connector for the motor phase windings. The module is compatible with external motor drives using a 10 to 48Vdc power supply. The External Control Module provides a standard system for rotor position sensing required by many brushless motor drives. Three hall sensors spaced 120 electrical degrees apart, sense a magnetic disk, which is synchronized to the rotor of the motor. The hall signals can be used to provide inexpensive speed feedback to the motor drive, or for more precise control a wide array of integral two channel quadrature encoder options are available. The quadrature nature of an encoder allows the user to determine the direction of motor rotation as well as speed. Environment: The NT Dynamo uses a TENV(totally enclosed non-ventilated) non-gasket construction. Installation and operating conditions should not exceed the recommended values for humidity and temperature. Contact the Hurst engineering department regarding any special installation issues you may have regarding vapors, oils or dust. Storage Temp.: 32-158oF (0-70oC) Humidity: 90% Max. Non-condensing Operating Temp.: 32-104oF (0-40oC) Power: Power to the motor windings is via the four pin connector. A regulated DC supply must be provided for the encoder and hall devices. Observe the correct polarity when making these connections. For maximum flexibility and noise immunity, the hall and encoder power supplies are separated. Excessive amounts of voltage ripple can cause shortened product life.

For cable runs longer than 3 ft, shielded wire is recommended.

The encoder outputs two or four quadrature signals from which direction and speed can be determined. These outputs can be used by an external drive to close the speed loop.
