Stepper motor - rotary - standard
ERIKS represents several stepper motor suppliers. All have their unique characteristics. Stepper motors has the property to develop a large torque without a separate gearbox at low speed. This makes them ideal for "direct-drive" positioning applications, such as Pick and Place, labelling and etc. Smooth running at low speed can be established by using micro steps. Stepper motors are also known as robust long life motors, because of the lack of brushess. We advice to contact us to make the right selection in combination with a stepper driver. Also you have to consider the stepper motor properties in your application such as noise, fibration and heat.
Below we have tried to give an overview when you select what?
| Supplier | Typical use | Peak

NEMA |
|---|---|---|---|
| IMS (1938kB) | Steppers with encoders | up to 7 Nm | 17, 22, 34, |
| MAE (3526kB) | Large quantities | up to 22 Nm | 17, 22, 34, 42 |
| Slo-Syn/Superior Electric (3829kB) | High quality motors | up to 37 Nm | 22, 34, 42 |
| Pacific Scientific (1253kB) | High Tech/quality motors | up to 40 Nm | 22, 34, 42 |

The MDrives
The MDrives are 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 MDrives allow the system designer to decide the best method of control. The MDrives integrated electronics eliminates the need to run the motor cabling through the machine, reducing the potential for problems due to electrical noise.
RS485
The RS485 standard allows one or more amplifiers to be connected (multi-dropped) using a cable length of less than 1200m. 31 Amplifiers and more 'master' may be connected in this way. The balanced differential signal transmission is less prone to interference and should be used in preference to RS232 in noisy environments. Although RS485 is commonly referred to as a 'two wire' connection, a ground return/shield connection is provided as a 'common', and in general this should be used in installations to provide additional protection against noise. Maximum data rate is about 10M bits/s and requirer 3 wires.

MDI23 Datasheet (177kB)
The MDrive NEMA 23 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 MDrive23 allows the system designer to decide the best method of control. The MDrive23's integrated electronics eliminates the need to run the motor cabling through the machine, reducing the potential for problems due to electrical noise.
The MDrive linear actuator version has a long life ACME Screw.
