The disclosure relates to a linear actuator including a base, a linear motor, a load cell and a rotary motor. The linear motor is disposed on the base and includes a fixed coil module and a movable magnetic backplane. The fixed coil module is fixed on the base, and the movable magnetic backplane is configured to slide relative to the fixed coil module along a first direction. The rotary motor is rotated around a central axis in parallel with the first direction. The load cell has two opposite sides parallel to the first direction, respectively. The movable magnetic backplane of the linear motor and the rotary motor are connected to the two opposite sides of the load cell, respectively. The load cell is subjected to a force applied thereto by the rotary motor and parallel to the first direction, and configured to convert the force into an electrical signal.

A modular motor assembly structure is disclosed and configured to couple with a drive shaft of an application device. The drive shaft includes a receiving slot. The modular motor assembly includes a main body and a combination key. The main body includes a shaft hole and a key groove. The shaft hole includes an opening and a central axis. The key groove is disposed on a side wall around the shaft hole and parallel to a central axis of the shaft hole. The combination key has a front end and a rear end. When one end of the drive shaft is inserted into the shaft hole along the central axis of the shaft hole, the combination key is at least partially accommodated in the receiving slot, and the front end faces the key groove. The combination key has a continuously increasing thickness from the front end to the rear end.
