IMS MDrive 34 Plus

The MDrive NEMA 34 high torque Integrated Motor and Driver is ideal for designers who want the simplicity of a motor with on-board electronics, but without the expense of an indexer on each axis. The low cost MDrive34 puts the system designer in the driver’s seat to decide the best method of control. The MDrive34’s integrated electronics eliminates the need to run the motor cabling through the machine, reducing the potential for problems due to electrical noise.

The MDrive34 uses a NEMA 34 frame size 1.8° high torque motor combined with a microstepping drive, and accepts up to 14 resolution settings from 1/2 to 256 microsteps per full step. Setup parameters include Microstep Resolution, Motor Rotation versus Direction Input and Run/Hold currents.These settings may be changed on-the-fly or downloaded and stored in non-volatile memory with the use of a simple GUI which is provided. This eliminates the need for external switches or resistors. Parameters are changed via an SPI port located on connector P2. Operating voltage for the MDrive34 ranges from +24 to +75 VDC.

The MDrive34 is available in three motor lengths: 24, 31 & 47. Interface connections are accomplished using 12" (30.5 cm) flying leads. Configurations include an optical encoder version and a control knob on the back for manual positioning.The MDrive34 is a compact, powerful and inexpensive solution that will reduce system cost, design and assembly time for a large range of stepping motor applications.
