Laravel - Table does not exist

I create a table with php artisan make:migration command. After that i edit the migration file to put the columns and insert standard data. After i run php migrate:referesh command and all good, i go to the database and the table is there with a correct name and data.

In database the table name is rolesStems.

I create a model like this:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class RolesStems extends Model
{
    protected $fillable = ['id', 'value', 'order', 'active','id_stem', 'id_role'];
}

And in my controller i do this:

use App\RolesStems as RolesStem;   
RolesStem::select('value')->where('active', '=', 1)->where('id_stem', '=', 1)->orderBy('id_role', 'asc')->get());

And i have this error:

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'dbname.roles_stems' doesn't exist (SQL: select `value` from `roles_stems` where `active` = 1 and `id_stem` = 1 order by `id_role` asc)

It put a unknown table name roles_stems, why?

I do this to other table, the same way, but with this table this happens.

What is the problem?
