minimum clearance location, and maximum at the maximum clearance location. When the extrusion gap clearance varies dynamically due to factors such as runout and vibration, the rate of damage to the rotary seal typically increases, because the extruded seal material experiences increased strain. 3 For example, see U.S. Patent 6,416,225.

The main principle of the concept is that maximum production is obtained from a ball mill when the mill motor power is at a maximum and consequently the specific energy consumption is at minimum. The maximum power point is dependent upon the feed material characteristics, mill liner conditions, grinding media charge and product size requirements.

Motor Sizing Basics Part 2: How to Calculate Load Inertia

Here's an example of a permissible load inertia chart for a BLE2 Series 200/400 W brushless motor (from our catalog). Since we've already calculated the maximum permissible load inertia values for each gear ratio, you don't have to. Try not to exceed these values. The motors may still work if these values are exceeded, but it cannot be guaranteed.

Universal motor - Wikipedia

The universal motor is a type of electric motor that can operate on either AC or DC power and uses an electromagnet as its stator to create its magnetic field. It is a commutated series-wound motor where the stator's field coils are connected in series with the rotor windings through a commutator.It is often referred to as an AC series motor. The universal motor is very similar …

Motor Vibration Analysis: Keeping it Simple | EC&M

More stringent specifications regarding motor vibration call for maximum velocity levels of 0.1 in./sec on the housing and 1.5 mils of displacement vibration on the shaft. The limits apply to a motor mounted on a seismic mass, and uncoupled or coupled to a piece of equipment in a way that eliminates any vibration in the driven equipment.

Determining Electric Motor Load and Efficiency - Energy

Most electric motors are designed to run at 50% to of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor 's efficiency tends to decrease dramatically below about 50% load.

ISO 10816 Vibration Severity Standards

ISO 2372 (10816) Standards provide guidance for evaluating vibration severity in machines operating in the 10 to 200Hz (600 to 12,000 RPM) frequency range. Examples of these types of machines are small, direct-coupled, electric motors and pumps, production motors, medium motors, generators, steam and gas turbines, turbo-compressors, turbo-pumps and fans.
