• Motor Vibration Analysis: Keeping it Simple | ECM

    Is the foundation or the motor frame vibrating at a higher level (more than 25%) than the motor? If so, there could be a weak motor base. Are any parts of the motor or shaft loose? Have any fan blades eroded or broken off? Is coupling lubrication satisfactory? If the above items are satisfactory, but vibration remains high, perform a thorough vibration analysis. You can diagnose a vibration ...

  • AB004 : Understanding ERM Vibration Motor .

    The ERM current is proportional to the torque 'load' seen by the motor. As vibration energy is taken out of the ERM system, the torque required to continue spinning the eccentric mass will increase, and so too will the current. This explains why the current draw of a loosely held vibration motor is greater than the current draw when the same motor is clamped tightly. In the latter case ...

  • Calculations | Simple Electric Motors

    Motor torque changes with the speed. At no load you have maximum speed and zero torque. Load adds mechanical resistance. The motor starts to consume more current to overcome this resistance and the speed decreases. If you increase the load at some point motor stops (this is called stall). When it occurs the torque is at maximum and it is called stall torque. While it is hard to measure stall ...

    Motor torque is produced where bal­ anced forces exist on either side of the rotor. If the forces of attraction are not balanced, then vibration results. This can be related to current or airgap variations in induction motors. Current Variations Due to Rotor or Stator Faults Consider a simple coil rotating through a magnetic field as shown in Fig. 2. It is well known that the force on a ...
