Control module cooling fan

A cooling system for an automatic control component includes a frame. The frame includes a front side, a back side, a first side wall, and a second side wall. The cooling system also includes a stay coupled to the frame. Additionally, the cooling system includes a locking mechanism coupled to the front side of the frame. The locking mechanism is configured to move between a locked position and an unlocked position to secure the frame to a control module assembly. Moreover, the cooling system includes a fan positioned within the frame. The fan is configured to cool internal electronics of the control module assembly and the fan receives operative energy from the control module assembly. The cooling system also includes a printed circuit board secured within the stay and configured to receive power from the control module assembly and supply power to the fan.

Industrial control component interface

A motor drive comprises a power sub-assembly and a control sub-assembly. The control sub-assembly includes components that may be accessed within the sub-assembly housing during installation and maintenance of the drive. A main circuit board is configured to define a high voltage region and a low voltage region. The high voltage region is isolated by an interior barrier of the housing so that the components can be conveniently accessed. An operator interface is provided in the control sub-assembly. An interface circuit board is also isolated by the barrier. Desired spacing between the interface circuit board and a surface of the interface is provided by integrally molded spring structures and plungers that interface with underlying switches.

Motor drive with inherent power isolation

A motor drive system includes a power sub-assembly that comprises power electronic components and driver circuitry for controlling gate drive signals to the power electronic components. A control sub-assembly is removably mounted to the power sub-assembly and comprises control circuitry for implementing a motor control routine for control of an electric motor. In operation, all control signals originate in the control-subassembly, and are transmitted via mating connectors to the power sub-assembly for driving the motor.
