The TB345-17SP is a special type of air conditioner motor designed for use in commercial air conditioning systems. The motor\'s primary function is to circulate cooled air through a building by spinning the internal fan. As its name implies, the motor is specifically designed for commercial applications, making it an important component in any HVAC setup.

The TB345-17SP features a totally enclosed fan cooled design which features a self-cooling stator winding and an integrated bearing system. The stator winding is designed to absorb thermal energy from the ambient air in order to keep the motor temperature in an efficient operating range. The integrated bearing system ensures maximum bearing life and minimal noise levels. Additionally, the motor is designed with a low noise output, with a maximum of 64 dB at a distance of 10 feet.

When installed, the TB345-17SP runs with three-phase power at 1725 RPM (revolutions per minute) on a two-pole motor. This makes the motor ideal for high-power applications, such as commercial air handlers, rooftop units, and refrigeration systems. The motor has a full-load efficiency rate up to 86.7%, and a starting torque of 250% of its full load rating.

In order for the motor to function properly, it must be connected to a compatible speed control system. The motor is controlled by variable frequency drives, or VFDs, which are used to adjust the motor speed. By adjusting the motor speed, it is possible to regulate the motor performance and drive the fan at different speeds in order to increase energy efficiency and improve air circulation. The drive also allows for different operational modes, such as variable speed for optimal system performance.

Apart from providing efficient and reliable performance, the TB345-17SP motor is also designed to be easy to install and maintain. The whole unit is designed to be lightweight, with a total weight of just 23 kg, and the built-in overload protection eliminates the need for additional protection devices. The integrated thermistor also provides protection against motor burnout, and the maintenance-free oil reservoir lubricates the motor for longevity. The motor also comes with a standard two-year warranty for peace of mind.

Overall, the TB345-17SP motor offers an efficient and reliable way to deliver cooled air to commercial systems. The motor’s lightweight design and built-in safety features make it an ideal choice for HVAC systems, and the compatibility with variable frequency drive speed control provides greater control over air circulation and energy efficiency.
