Page 4: Please Read Surely The Following Precautions
Please read surely the following precautions Introduction We thank you for your adoption of Toyo Denki ED Motor (permanent magnet type synchronous motor). This Manual shows handling method of ED motor and precautions on use for customers having general knowledge on permanent magnet type synchronous motor. Before use, please read this Manual carefully until getting of enough knowledge on our ED motor and use it when it is in optimum condition. - Page 5 ! Danger ・Do not operate the motor in state that the cover of terminal box is removed. After work, fit the cover of terminal box at the original position. Otherwise, that could result in electric shock. (Piping, wiring) ・Connection with power supply cable should be done in accordance with connection diagram or Instruction Manual.
- Page 6 ・Repair and disassembly should be done by qualified expert. Otherwise, electric shock, injury, fire, etc. could occur. EDM Series ED motor is the most suitably designed motor for Inverter drive by Toyo Denki having high level technology in rotary machine and control equipment.

Page 7: Preparation For Operation
I. Preparation for operation 1. Checking at arrival of motor When the ordered motor arrived, please check paying attention to the following points. (1) Check the motor with our invoice separately sent. (2) Check the motor for damage, rusting, dropping of accessories, etc. (3) There is a case that the rotor of motor is fixed in order to prevent the bearing from being damaged during transportation. - Page 8 2.2 Connection with counterpart machine (1) Foundation work In order to minimize the vibration and misalignment during operation, strong foundation is required. If foundation is incomplete, machine will vibrate and bearing life will be shortened, to which please pay attention. The most ideal foundation in order to prevent generation of vibration is a strong concrete foundation but if such concrete foundation cannot be made because of counterpart machine and...
- Page 9 (3) In case of belt drive Set the counterpart machine shaft and motor shaft accurately parallel and apply the belt in such a way that both pulley centers coincide each other. The belt is apt to be stretched too much however, excessive stretching will damage the bearing and cause unexpected accidents such as breakage of motor shaft, etc., to which please pay attention.

Page 11: Electric Wiring
3. Electric Wiring 3.1 Terminal box There are main terminal box for motor main body terminals and thermistor, and auxiliary terminal box for electric fan. Connect external wirings correctly and firmly. Connection with pulse oscillator of motor side is connector-connection. 3.2 Connection diagram Fig. - Page 12 3.3 Direction of rotation (1) Direction of rotation must be correct. (2) Direction of rotation of the motor is expressed as seen from the shaft end of drive side. Standard direction of rotation of the motor is counterclockwise (CCW) in case that the phase sequence of power supply side is R, S, T and when these phases are connected with the motor terminal symbols U, V, W.

Page 13: Trial Operation And Ordinary Operation
II. Trial operation and ordinary operation 1. Before powering All of your purchased motors from us passed severe tests at our factory however, they may have a possibility of being damaged during transportation or affected by long storage, and so carry out following checking, confirmation before starting of operation. -
Page 14: Maintenance, Checking
III. Maintenance, checking In order to prevent accidents in operation of the machine, daily monitoring or checking is required. 1. Daily checking By touching and hearing, check the vibration and sound at the time of starting and during operation of the machine and confirm that there is no abnormality. User is recommended to put the status of operation on record. - Page 15 3.2 Grease replenish type bearing For the motors of EDM43 or over, kind, quantity and interval of replenishing of grease are indicated on the name plate. (1) Replenish the grease during operation at every replenishment interval (operation time) indicated on the name plate. In case that the net operation time is short due to short-time or repetitive operation, grease should be replenished in such a way that the elapsed time including stoppage will not become twice or more of the interval indicated on the name plate, or at least every 6 months - one year.

Page 16: Checking Of Accessories
3.4 Sound of bearing (Grease replenish type) Sound of bearing during operation is classified as follows. (1) Normal sound The normal sound is continuous one. The race sound, jarring sound and retainer sound are considered as normal. The jarring sound may be misunderstood as an abnormal noise but it does not mean the abnormality of bearing. -
Page 17: Preparation For Operation
IV. Storage 1. Storage (1) In case that the motor is stored for 3 months or longer till the initial operation after receiving it or its operation is stopped for 3 months or longer, take the following steps. 1) Storage : The motor should be placed in the same posture with correct installation state, covered with waterproof sheet, and be kept at a dry place. -
Page 18: Disassembly, Assembly
V. Disassembly, Assembly This motor incorporates permanent magnet in its rotor. Owing to this composition, pulling out of the rotor from the stator is quite difficult. Therefore, do not pull out the rotor from the stator at the time of disassembly/assembly of motor, such a case of replacement, etc. of bearing. Replacement of bearing can be carried out keeping the rotor inserted in the stator. - Page 19 (5) Loosen about 3 turns the 2 setscrews fixing the pulse oscillator rotor to the motor shaft and remove pulse oscillator. (Do not take off the setscrews.) However, an adhesive (TB1342H) is used to prevent the set screws from loosening. Before removing the set screws forcibly, warm them up to about 100°C using a thin soldering iron and then remove them.
- Page 20 The shaft runout correction method is as follows. Non-magnetic (a) If the encoder mounting shaft is integral with the type dial gauge motor shaft (Refer to Fig.12 (a)), adjust by tapping the shaft end with a plastic hammer (Less than 2LB) and a rod of soft material that does not damage the shaft.
- Page 21 1.2 Load side (1) Remove the bearing outer cover of load side. (For EDM22 or less, this cover is unified unit with bracket.) In addition, since the V ring is attached in the case of waterproof specification, remove the V ring. Refer to the outline drawing to identify the type of V-ring. (2) Pull out the slinger of bearing outer side of load side from the shaft.
