There are several different types of V Ribbed Belt for use on electric motors:

Standard V-belts, used in the majority of belt drives, have a trapezoidal cross section that fits tightly into a sheave to increase friction and power transfer capability. V-belt drives can have a peak power efficiency of 95 percent or more at the time of installation. The efficiency rating depends on pulley size, pulley wear, V-belt alignment, transmitted torque, and if belts are under- or over-sized for specific load requirements. If the belt is not periodically retensioned, power efficiency can deteriorate by as much as 5 percent over time due to slippage.

Notched belts have grooves, or notches, that run perpendicular to the belt’s length, which reduces the bending resistance of the belt. Notched belts can use the same sheaves as most standard V-belts. Notched belts run cooler, last longer and are about 2 percent more efficient than standard V-belts. They should be considered as replacements for V-belts wherever possible.

Synchronous belts, which have teeth, are about 98 percent efficient and maintain that efficiency over a wide range of loads. Synchronous belts typically require less maintenance and retensioning than V-belts and notched belts and can operate in wet and oily environments. However as stated, they require the installation of matching tooth-sized drive sprockets, requiring motors running standard V-belts to be retrofitted before synchronous belts can be used. Synchronous belts are also called cogged, timing, positive-drive and high-torque drive belts.
