Summary:  We consider an abstract version of a Dirac operator which describes a Hamiltonian of the chir al quark soliton model (CQSM) in nuclear physics. The mass term of the Hamiltonian describing the concrete CQSM is a matrix-va lued function. Hence, the abstract CQSM Hamiltonian has structures different from the stand ard Dirac operator. We discuss the nonrelativistic limit of the abstract CQSM Hamiltonian and show that a binding potential appears as an effective potential. As an application of this abstract result, we derive the nonrelativistic limit of the concrete CQSM.
