The synchronous belt system initially cost $678 more than the Vbelt system. If slip is 5%, energy costs $0.08/kWh, and the fan operates 168 hr/week, the synchronous belt yields predicted savings of $2152/year (see motor when a synchronous belt drive system is used instead of a conventional Vbelt drive system.

The low voltage synchronous motor is expected to dominate the synchronous market owing to a wide range of applications of low voltage over the high voltage synchronous motors. Based on application, the synchronous motors market is segmented into compressors, pumps, fans, extruders, mixers, conveyor belts, and others application depending on
B. Synchronous versus Induction Motors . Prior to starting system design, the type of motor to be utilized had to be determined, induction or synchronous. Induction motors are simpler, lower in cost, and easier to control; synchronous motors are marginally more efficient and provide reactive power (VARs) to improve system wide power factor.

Subject: This twopage abstract provides tips for plant managers on improving performance of industrial motors by designing beltdrive transmission systems for high efficiency, low noise and maintenance, and cost savings.
“In most commercial applications the Vbelt drive is the critical link and the only mechanism for mechanical transfer of power from the electric motor to the driven shaft/fan/blower,” said Don R. Sullivan, sr. product manager Belt Drives/Power Transmission Solutions for Emerson Industrial Automation.
Electric motors account for roughly $85 out of every $100 of a manufacturing/process plant's electrical bill. {C} Here is a breakdown of how much one 200 hp, 1,800 rpm and 460 V TEFC motor costs in power in a calendar year (7,200 hours of operation): Average cost of power in the United States: $.068/kWh.

Synchronous motors are inherently not able to selfstart on an AC power source with the utility frequency of 50 or 60 Hz. As stated in Chapter 1, this is because synchronous motors can develop a torque only when running at the synchronous speed.However, the synchronous speed for the utility frequency is too fast for the rotor to synchronize for

lower for a synchronous belt drive. As with Vbelts, synchronous belts require pretensioning and tension maintenance, although we would agree that the frequency of retensioning may be less. This is due to minimal belt seating in the pulley grooves, low growth tensile cords and closer manufacturing tolerances associated with
Electric motors have a range of industrial applications, including the operation of pumps, compressors and fans. Motors use substantial energy and can incur significant running costs, meaning great potential for savings. Most motor energy consumption in Australia is midsize motors with output power between 0.75kW to 375kW.
Belt Drive Efficiency. Efficiency describes the ratio of output power to input power. Vbelts suffer from belt and pulley friction, bending, elongation and decreased pretension, resulting in loss of efficiency. Vbelts achieve an

EC motors are brushless and are simple in design, lending them to long term use. EC motors are quickly becoming the new industry standard for air handler fans and other applications because of their amazing efficiency. PSC motors dissipate heat due to their capacitors which reduces their overall efficiency to around 50%.
This belt runs on the same pulleys as a standard Vbelt, so upgrading is a simple process of changing the belt without incurring the cost of new components. Unlike a synchronous belt, a cogged Vbelt provides better vibration damping where excessive vibration is a concern. Cons. Initial cost of raw edge vbelt is higher although return on
Feb 1, at 20:11. Yes, those are considerations. It seemed to me that you already had your control circuit designed. Unlike a DC circuit where you can use a diode, an AC circuit usually uses a series RC snubber across the relay contact to reduce arcing. You should factor that in. jwh20. Feb 1, at 20:16.

Synchronous Belt (also commonly referred to as timing belt) Vbelt is a friction device and works on the principle of the wedge. It relies on tension to create friction on the sidewall of the sheave to transmit power. Vbelts allow slippage which can be desirable and intended in drive design. For example, in a mower deck where the belt
