A high performance external motor drive specifically designed to optimise operation of five of Crouzet's ultra-quiet DCmind brushed motors ranging in size from 42-62mm diameter and in power from 15-100W, has been introduced by Crouzet, the BDE PRO.
This new analogue controller is suitable for use in a variety of markets including medical, access control, commercial and industrial applications, and is well-suited for rapid prototyping for new product development.
The 84855104 BDE PRO controls motor speed and torque in a compact panel-mount package that measures just 5.1x3x1". Performance characteristics include a power range of 25A peak current and 15A continuous current while supporting both Hall-effect sensor and incremental encoder type feedback. Other features include a red/green LED that indicates operating status and three operation modes for current, encoder velocity or duty cycle.
Robert Derringer, Channel Management and Product Marketing Director for Crouzet North America, said: "The BDE PRO is Crouzet's highest functionality motor controller and is specifically 'tuned' to optimally drive DC brush motors at a high switching frequency."
Derringer added: "Although intended as an optional counterpart for Crouzet DCmind brushed motors, the device is easily configured for use with DCmind brushless motors, and can also be used for many other motor types with simple changes in DIP switch and potentiometer settings."
When used with Crouzet DCmind motors, the cost effective system helps customers more precisely control the DCmind motor series, which is increasingly in demand for applications where silence, long life, efficiency and low EMC levels are required.
The unit's powerful control capabilities meet a variety of application needs. In the case of medical applications where a constant gentle velocity may be required, the BDE PRO can drive the motor at a gentle pace while being able to stop if needed. Its 4-quadrant operation allows the motor to go clockwise and counter clockwise quickly, and to stop immediately as needed, an important requirement in medical applications such as imagery, surgical equipment, mobile robotics, and precision pumps.
The new drive is fully protected against overvoltage, under-voltage, overcurrent, overheating and short circuits across motor, ground and power leads. It can interface with digital controllers or be used stand-alone, and requires only a single unregulated DC power supply. Loop gain, current limit, input gain and offset can be adjusted using 14-turn potentiometers. An offset adjusting potentiometer can also be used as an on-board input signal for testing purposes. The BDE PRO is certified under UL, cUL, CE and RoHS.
