  • Patent number: 11560904
    Abstract: A modular fan cover assembly for inclusion on an electric motor is selectively configurable for degrees of reduced noise operation. The modular fan cover assembly includes a plurality of cooperating components arranged to direct fluid communication through the assembly. The components may include, for example, a fan cover defining a fan chamber for enclosing the fan, an inlet cover including an inlet chamber and a plurality of inlet apertures, and a silencing insert selectively includable with the fan cover assembly that may include one or more silencing features. The selective combination of the components can redirect airflow through various turns or bend in the modular fan cover assembly to trap or suppress noise propagating from the electric motor. The modular fan cover assembly may be operatively equipped with a blower assembly.

  • Publication number: 20200408252
    Abstract: An anti-friction insulated bearing system, including a bracket disposed about a motor driveshaft and a bearing disposed within the bracket configured to support the driveshaft for rotation. The system also includes an outer bearing cap disposed proximal a drive end of the bracket and an inner bearing cap. The system further includes an insulation sleeve disposed within the bracket proximal the bearing. The outer bearing cap, the inner bearing cap and the insulation sleeve are configured as modular components of the system. The modular insulation sleeve allows the use of standard anti-friction rolling element bearings. The modular components have common inner and outer bearing caps that can be used across a multitude of configurations with a minimal number of parts.

  • Patent number: 10833563
    Abstract: A totally-enclosed fan-cooled motor, including a stator provided in a closed motor housing, a rotor provided to the stator and mounted to a rotation shaft, a pair of bearings for holding a drive side and a non-drive side of the shaft, an external fan provided on the non-drive side of the shaft and outside the motor for sending wind to the motor housing, an air deflector mounted to an endplate disposed on the drive side located on an outer side of the bearing and the endplate holding the drive side of the shaft, outside the motor and proximal the bearing for cooling the bearing holding the drive side of the shaft. The air deflector includes a plurality of faceted surfaces at obtuse angles to one another about a periphery of the air deflector to deflect wind across the endplate and the drive side bearing.

  • Patent number: 10023207
    Abstract: Embodiments of the present invention generally relate to a zip line or trolley system kit for propelling a person or an object using gravity along an extended cable line suspended between two trees or towers. The zip line or trolley system may include an easily installable support harness assembly, a braking system and a removable seat fixture to provide for the zip line system to be completely portable to be carried, installed and taken down in remote locations.

  • Publication number: 20150189429
    Abstract: A method and apparatus for the production of sound that may be in the form of musical tones using a slackline as the vibrational sound source and a vibrational tracking clip with an electroacoustic transducer such as a microphone, pickup or piezoelectric crystal mounted in close proximity to the slackline to transmit the vibrational sound waves from the slackline to an amplifier, a computer, tablet, mobile device, a digital recording system or other digital device and speaker to record, playback and/or modify the sound using sound effect systems and/or software applications. The present invention is further related to a vibrational inducement apparatus to induce a vibration in the slackline and tone conditioning software applications implemented on a digital device having a microprocessor, memory and storage and a measuring device that measures distance, angles, position and/or movement and translates sound signals to musical tones based on these measurements.

  • Patent number: 8985027
    Abstract: A zip line or trolley system kit for propelling a person or an object using gravity along an extended cable line suspended between two trees or towers. The zip line system having a frame with one or more wheels, an adjustable length seat, a handle and a braking system for slowing the speed of descent of the zip line system. The trolley system having at least two wheels spaced apart at a suitable distance to increase ride smoothness and improve sliding of the zip line system along the extended cable. An actuator of the braking system allows for the rider to control of the speed of descent of the zip line system.

  • Patent number: 6798096
    Abstract: The present invention provides for a system and method for facilitating cooling of a totally enclosed motor. A first thermal barrier is coupled to a first end bracket and is operable to insulate bearings from internal heat produced by the motor. Either an external fan located opposite the drive end of the motor, an externally mounted blower, or free ambient air convection may be employed to provide cooling air to the motor. An air deflector is coupled to the drive end of the motor to capture the cooling air and direct it as high velocity air over the first end bracket thereby keeping the bearings supported within the first end bracket cool. Alternatively, an external fan may be coupled to the drive end of the motor to provide cooling air to the first end bracket.
