Product Description:
The MAC041B-0-BS-4-E/050-A-1/WI670LV is a servo motor supplied by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it converts commanded current from a drive amplifier into controlled torque for positioning and speed-regulated motion in compact industrial axes. Because it is intended for analog servo systems, the amplifier can regulate current continuously to help produce smooth response as the load changes. This arrangement supports repeatable movement in pick-and-place units, feed systems, and other automation equipment that require steady tracking. Its compact format is also useful where mounting space is limited and the axis must still respond quickly to command changes.
A standard blocking brake keeps the shaft fixed whenever the drive is disabled, which helps hold vertical loads or geared axes in place without external clamps. Brake holding action is useful during power loss or intentional shutdown, especially when the load could drift under gravity or gearbox backdrive. Heat is removed through natural convection, so no auxiliary fan is needed and enclosure airflow stays simple. The motor has a size of 041 and a frame length of B, which suit compact machine layouts. Power conductors connect through a plug with a connector on side A, allowing cable routing to follow the machine structure with less interference from moving parts.
For closed-loop control, the motor uses tacho feedback with an incremental or absolute encoder, giving the drive a speed signal or position signal from the same housing. The position channel uses an incremental encoder with standard mounting, which keeps the feedback unit centered at the drive end for reliable signal transmission. Using integrated feedback reduces the need for separate external sensing hardware and keeps cable routing more compact around the axis. These feedback elements work with analog amplifiers that use sinusoidal commutation, helping the drive maintain rotor alignment during acceleration, constant-speed operation, and deceleration. The feedback arrangement also supports stable speed control and consistent position correction as load conditions change.
