Designing with Belts and Pulleys

The presence of ozone can be detrimental to the compounds used in rubber synchronous belts. Ozone degrades belt materials in much the same way as excessive temperatures. Although the rubber materials used in belts are compounded to resist the effects of ozone, eventually chemical breakdown occurs and they become hard and brittle and begin cracking. Get price

ABB acquires ring motor business from Alstom

The gearless motor - also called wrap-around motor or ring motor - is a very large synchronous machine which uses power electronics and a magnetic field to control the speed of the motor rotation. With no mechanical interaction between the stationary and rotating parts, there is a significant reduction in the amount of energy used, fewer parts and higher reliability. Get price

Phase Margin

1. Gain margin Gain margin is defined as the amount of change in open-loop gain needed to make a closed-loop system unstable. The gain margin is the difference between 0 dB and the gain at the phase cross-over frequency that gives a phase of −180 . If the gain | G H (j ω) | at the frequency of ∠ G H (j ω) = − 180 is greater than 0 dB as shown in the left of Fig. 2.25, meaning a Get price

Belts and Pulleys

Minimum wrap angle is a measure of how much the belt wraps around the smallest pulley. Belt length is how long the belt would be if cut and laid flat. Finally, in the case of toothed belts (also called synchronous belts) the pitch is the number of teeth per some length—so a 3-mm pitch means that the belt has one tooth every 3 mm, for example.
