The BXT flat, brushless dc servo motors with compact short design includes a diameter-compliant integrated speed controller. With an additional attachment length of 6.2 mm, the motor + speed controller combinations are available with the same installation space as the products with the IEF3-4096 (L) integrated encoder. Through synergy effects with the encoder variants, the controller is fully integrated in the robust motor housing. The motors can be put into operation quickly with motion manager software. The controller can be combined with the 2214…BXT H, 3216…BXT H and 4221…BXT H housed BXT motors.
