Dc brush micromotors - Import export

BMSD‑40Modbus controllers are designed to control a DC brush motor with rated current up to 40 Amp, maximum limit current 100A. The controllers regulate the motor speed, set the direction of rotation, provide speed stabilization when using Hall sensors, and control acceleration and deceleration. Thanks to the current limiting function, the controllers protect the motor from overloads. The controllers are controlled via the RS ‑ 485 interface using the Modbus RTU or ASCII protocol or by external signals supplied to the controller inputs. The main parameters of controller BMSD‑40Modbus - Hardware short-circuit protection (time operation 15 μs): 100 Amp - Phase current limitation (response time 5 s): 2...60 Amp - Communication interface: RS-485, Modbus – ASCII or RTU

BMD‑40DIN are speed drivers for DC brush motors. Speed, acceleration and deceleration time are adjusted by the internal potentiometers on the frame of the driver. Speed also can be adjusted by an external potentiometer or by an analog proportional signal 0 ‑ 5 VDC. Direction can be changed by external signal (clean contact) “DIR”. For safety reasons the drivers provide adjusting of a maximum continuous motor current, this function protects motors from overcurrent. There is an emergency input HARD STOP in the drivers. It is intended for mechanics protection - the motor stops immediately in case the protection circuit is broken. Adjustment of a threshold of operation of protection is carried out by a potentiometer of "Current adjust". With its help maximum permissible current for each specific engine controlled by the unit is set. The limitation current value can be set precisely. Exceeding of this current during no more than 5 sec will lead to transition to emergency operation.

BMSD‑20Modbus controllers are designed to control a DC collector motor with rated current up to 20 Amp. The controllers regulate the motor speed, set the direction of rotation, provide speed stabilization when using Hall sensors, and control acceleration and deceleration. Thanks to the current limiting function, the controllers protect the motor from overloads. The controllers are controlled via the RS ‑ 485 interface using the Modbus RTU or ASCII protocol or by external signals supplied to the controller inputs. The main parameters of controller BMSD‑20Modbus Hardware short-circuit protection (time operation 15 μs): 30 Amp Phase current limitation (response time 5 s): 1...20 Amp Communication interface: RS-485, Modbus – ASCII or RTU
