In a method of manufacturing a magnet embedded core (1), creation of unnecessary resin from the resin for fixedly securing the magnet is prevented. The method includes a resin charging step of charging resin material (33) in solid form into the magnet insertion hole; a melting step of melting the resin material (33) in the magnet insertion hole, and a pressurization step of pressurizing an interior of the magnet insertion hole (3). The melting step includes melting the resin material (33) at least partly by preheating and inserting the magnet (4) into the magnet insertion hole (3).

An electrically actuated parking brake has a single electric motor producing a torque, a first torque limiting device with a first spring force, and a second torque limiting device with a second spring force. The first torque limiting device fully transmits a first portion of the torque to a first spindle until a first clamp force overcomes the first spring force and the second torque limiting device fully transmits a second portion of the torque to a second spindle until a second clamp force overcomes the second spring force. When the first clamp force overcomes the first spring force and the second spring force overcomes the second clamp force, the first portion of the torque that exceeds the first spring force is transmitted to the second spindle by the second torque limiting device.

A magnet embedded core is manufactured in a stable manner by preventing an excessive pressurizing force from being applied to the laminated iron core and performing the clamping with an appropriate pressurizing force so that the leakage of the resin out of the magnet insertion holes can be minimized, and the reduction in the geometric and dimensional precision of the laminated iron core may be suppressed. An electric die clamping device is used, such that a laminated iron core is placed on one of a fixed die and a moveable die and upon clamping by the die clamping device, the other of the fixed die and the moveable die is caused to abut onto an end surface of the laminated iron core to close openings of magnet insertion holes and pressurize the laminated iron core in a laminating direction.
