1. A percussive massage device comprising:
a housing having three handle portions configured to be grasped by a user and connected to each other in a triangular shape;
a motor that includes a rotor, wherein the motor is disposed in a joining portion of two of the three handle portions;
a push rod in a unitary body having a proximal end operatively and directly connected to the motor at a connection portion at a center of an axis of the motor, wherein the push rod includes bearings at its proximal end and is configured to reciprocate in response to activation of the motor, and wherein the push rod extends out from a center of the motor, partially disposed over the motor;
a massage attachment coupled to a distal end of the push rod, wherein the proximal end of the push rod extends from the connection portion of the motor to the distal end of the push rod in an arc shape such that the connection portion of the motor, at which the proximal end of the push rod is connected, is offset from a reciprocating path that the distal end of the push rod travels;
a sensor configured to detect a rotor position of the rotor;
a force meter configured to determine a force exerted by the massage attachment on a user's body part; and
a controller configured to:
receive the rotor position and determine a rotational speed of the motor based on the rotor position,
increase or decrease an operating power of the motor to respectively increase or decrease the rotational speed to maintain a percussive effect, and
execute a protocol comprising a first step for running the motor at a first rotational speed for a first duration and a second step for running the motor at a second rotational speed for a second duration, wherein during each of the first duration and the second duration, the controller is further configured to:
determine that a first force measured at a first measurement time is smaller than a second force measured at a second measurement time, wherein the second measurement time occurs after the first measurement time, and
increase, based on the determining, the operating power of the motor to maintain the percussive effect during a respective one of the first duration and the second duration, wherein the increasing of the operating power of the motor comprises raising the rotational speed of the motor to match a respective one of the first and second rotational speeds.
