Assisted racking of digital resistance includes detecting a state of a cable. A motor is mechanically coupled to the cable to provide resistance during an exercise by tensioning the cable. It further includes determining completion of the exercise based at least in part on the detected state of the cable. It further includes selectively removing resistance from the cable based at least in part on the determination that the user has completed the exercise.

A packaging device includes a conveyance mechanism, a guide portion and a control portion. The control portion is configured to cause a first section of a film to be bonded to a base, cause the conveyance mechanism to convey the base toward a downstream side in a conveyance direction, move the guide portion along a movement path, cause the conveyance mechanism to convey the base toward the upstream side, cause a second section of the film to be bonded to the base, and cause the film to be moved in an opposite direction to a feeding direction at any time during a period after the first section is bonded to the base and before the second section is bonded to the base, the feeding direction being a direction in which the film is fed out when the base is conveyed.

An output-torque estimation unit obtains a value of a current input to a motor, from a power converter, and calculates an estimated output torque value which is an estimated value of output torque of the motor, from the obtained value of the current. A load estimation unit estimates a load value of a hanging cargo based on the estimated output torque value which is calculated by the output-torque estimation unit, a speed reduction ratio of a speed reducer, an effective radius of a winch drum, and the winding number which is set by the number setting unit.

A motor assembly and method for measuring brake backlash using onboard components of the motor assembly. The method includes engaging a brake of the motor assembly, applying torque to an output shaft of the motor assembly in first and second rotational directions and measuring a difference in angular position of the output shaft using a position feedback device of the motor to calculate brake backlash.

A rotor for an LSIPM comprises a plurality of permanent magnets defining a number of poles (P) of the LSIPM, and a plurality of rotor bars spaced about the rotor defining a rotor bar area (BA). The rotor bars are formed of a conductive material having an associated conductivity (.sub.RB). End members are disposed on axial opposite ends of the rotor core. The end members are in electrical contact with the rotor bars. The end members are formed from a material having an associated conductivity (.sub.EM). Each end ring member has a minimum geometric cross sectional area (ERA) and outer diameter that generally corresponds to the rotor core outer diameter. The ERA is greater than 0.5 times the rotor bar area per the number of poles (BA/P) times a ratio of the rotor bar material conductivity to the end member material conductivity (.sub.RB/.sub.EM).
