When evaluating three-phase motor winding data, an often overlooked factor is the no-load amp (NLA) rating. If the NLA is more than 20% lower than expected, that usually indicates the airgap density is conservative. If more than 20% higher than normal, expect the airgap density (AGD) to be on the high end of normal ranges. As a loose guideline, AGD is generally between 45 and 55 kilolines of flux per square inch (0.70 to 0.85 Tesla). "Low" FLA may indicate AGD below 40 kilolines of flux/ in2. "High" FLA is likely to be 60 kilolines of flux/in2 or higher. In such cases, always use the EASA database to compare the AGD of motors with the same rating and core dimensions.

Social media can help your business a great deal, but there are also drawbacks. One negative is an unhappy customer who chooses to air his/her grievances online. Following are four things Forbes.com recommends that you keep in mind when responding online to a dissatisfied customer.

1. Respond in a timely manner. A quick and timely response is important. Respond within a few hours or at least the same day.
2. Prove that you are listening. In your response, restate the reviewer’s grievance. This shows the reviewer that you have taken the time to read and internalize their concerns. Use their name, as well, to acknowledge them and to help make it a personal response.
3. Keep it positive. Even if you are sure the reviewer is not telling the truth about their experience or even about being a client or customer, keep it positive, and offer to take action to resolve the issue. If you want to point out that you have no record of them doing business with your company, do so, but keep it light, and offer the same response you would any other reviewer.
4. Offer contact information. Once you have shown the reviewer that you value their opinion and are willing to take appropriate action, it’s time to provide your contact information. That contact information could be a number to a customer service line, or you may request that the customer send you a private message.
