The speed of a motor is varied in an electrical submersible pump well to analyze and avoid excessive vibration. A vibration sensor near the motor senses vibration in the well. The vibration of the assembly varies with many factors, including the length of the tubing, the locations of the packers, and the use of centralizers relative to the casing. The assembly has critical frequencies at which vibration increases to an undesirable level. These critical frequencies are determined and programmed into the variable speed drive so that they may be avoided. Avoidance of the critical vibration frequencies prolong the life of the downhole equipment, including that of the motors, pumps, seals, and sensors.

A starter for cranking an internal combustion engine includes a device for absorbing a rotational torque exceeding a predetermined level. In this device, a laminated body composed of fixed disks and the rotatable disks is used. A frictional force in the laminated body is preset by a spring member pressing the laminated body in the laminated direction.

To give a proper surface hardness to an internal gear portion of the rotatable disk and to give an abrasion-resistive property to a portion contacting the fixed disk, the rotatable disk is subjected to soft nitriding treatment. Thus, a stable frictional force is secured in the laminated body, and a long life of the excessive-torque-absorbing device is realized.
