BLDC Traction motors with brake and encoder
The brushless DC motors of the BL Traction series are made in 3 sizes: 80 – 95 – 120 mm and have the following characteristics:
- 3ph BLDC sensorless
- dual voltage 48Vdc/ 24Vdc
- Motor power 320W-650W-1320W
- IEC metric flange and shaft
- lnsulation class F
- Protection class IP65
- Safety brake 48Vdc/24Vdc
- Encoder high resolution
These motors have been designed to have the electromechanical brake as standard included inside the motor casing, and thanks to the seals placed on the output shaft and on the rear cover, as well as having blind holes on the flange and the rear side, motor and brake are protected from any external agent, guaranteeing an IP65 protection class.

IEC duty cycle ratings
| S1 | Continuous duty. The motor works at a constant load for enough time to reach temperature equilibrium. |
| S2 | Short time duty. The motor works at a constant load, but not long enough to reach temperature equilibrium, and the rest periods are long enough for the motor to reach ambient tempera- ture. |
| S3 | Intermittent periodic duty. Sequential, identical run and rest cycles with constant load. Temperature equilibrium is never rea- ched. Starting current has little effect on temperature rise. |

Description
The MEHR 22 is a optical magnetic incremental encoder; he is a reliable hollow shaft encoder and can be fixed in a different sizes of electric motor.
This encoder is developed for brushless motor, motor feedback and the rotazional speed control.
The encoder MEHR 22 is a real time system for speed and position application.
This encoder provide two square wave outputs in quadrature (A-B 90° degrees) for the direction and counting information and a third channel with lap pulse (zero mark).
Additional there is a magnetic encoder integrated which provide UVW signal as commutation. The resolution of encoder is determined by the number of cycles for revolution (CPR).
Power supply and signals are provided by a 11 pin JAE connector.
Main specifications:
- Output channels encoder: A-B-I and /A-/B-/I
- Optional channels hall sensor: U-V-W and /U-/V-/W

Summary
The BLD60 DIGITAL PLUS servo drives is a fully digital drives operate in torque, velocity, or position mode and employ Space Vector Modulation (SVM), which results in higher bus voltage utilization and reduced heat dissipation compared to traditional PWM. The drive can be configured for a variety of external command signals. Commands can also be configured using the drive’s built-in Motion Engine, an internal motion controller used with distributed motion applications. In addition to motor control, these drives feature dedicated and programmable digital and analog inputs and outputs to enhance interfacing with external controllers and devices.
Network communication is accomplished using either RS-485/232 or Modbus RTU.
